Just wanted to opt in and say that wlan_rx_wake is also my highest wakelock.
So there definitely seems to be something going on. Thx for your efforts with wireshark.

Are there any android based sniffer that we can also use?

shark for root and open it up with shark reader. Hmm, the packets seem to be coming from my housemate's PC. Null packets that keep coming to my phone :S

Broadcast??

445 being SMB/netBIOS (old crap)

80 is the HTTP port, dunno what windows would be doing with that.

Windows is verbose and messy, generally spams the network with junk :(

Yeah, not sure why it's the only system sending junk packets to my phone thus waking it up :/

I can post logs here if anyone is interested to analyze them.

Might be the way the network shares are set up, but I just checked my own wakelockes as my battery has been dropping hard as well, 7h+ of deleted wake locks, aka wifi stuff and another hour plus of wilan wake, wifi sleep policy is default. So something is not quite right with the wifi.

I am on the newest cm9 nightly and rc6 version.

Did this happen in the previous build as well? It seems to happen to me in the previous build as well.

Thanks you guys' efforts above.

I am coming from other kernels. Did kernel cleanup and wipe cache and delvic cache before flashing siyah kernel.

I didn't experience Wi-Fi preventing deep sleep issues in the kernels I am coming from. So perhaps there is a bug in siyah 's rc6 release?

:confused:

Hey guys, I'm having problems with my auto-brightness, it doesn't seem to work it just keeps my last set brightness ex: set full to -> auto keeps full even in no light environnement. Using siyah 3.1rc6 NEAT LP8. I can't seem to set the brightness as low as in gb with the extweak... I press save and apply and it does nothing...

edit: nvm fixed by switching the the battery friendly profile :D

Wow that's way too much, do you get decent signal strength to WiFi? Maybe that could help.

Yes, the signal strength is decent. Almost full bars. I'm guessing its the DHCP messing up causing the wakelocks, and after disabling DHCP, my housemate's PC sending NETBios requests would be the next problem.

I wanna ask Wifi related.
Not wakelock/battery drain issue. It just keep disabling on its own regardless my settings and also sometimes need reboot in order to connect to AP, otherwise it just "obtaining IP" or "connecting" all the time...

How to fix that. Its been like that even before I flash Siyah in my stock LPS rom...

Maybe try changing your modem?

Clarification please

Alright, I'm a semi-n00b at flashing roms, just end-user knowledge.
I'm currently using cm9 (from 9th april) + rc6(not latest, and dont know which one for obvious reasons :p).
Everything seems fine for now but i want to flash the latest cm9 nightly and siyah.
My last experience of doing this was horrible, cuz of the storage issues.
Im downloading update-cm-9-20120421-NIGHTLY-galaxys2-signed.zip right now and wanted to know whether its got no issues with latest siyah.
Anyone?
btw is GM's website the only way to download it?

    Features:
    • based on JB sources
    • DISABLED CAP_ERASE (No superbrick bug)

    • Dual booting support for all supported ROM types. See droidphile's post for Dual Booting FAQ
    • Custom CWM touch recovery with swipe gestures and double-tap selection
    • 6-steps CPU freq
    • 5-step GPU frequency levels. VPLL Mode to have additional frequency steps. defaults frequencies: 66-108-166-267-330.
    • Auto-root. You can also remove root via STweaks app and install it without rebooting your phone again. Auto-root can be disabled as well.

    • Tweakable vitalij's value (set to 5 as default)
    • Adjustable touchpad led brightness
    • Fixed fuelalert wakelocks
    • You can completely disable android logger using STweaks app
    • Faster charging for misc and USB modes. There are 3 modes (AC, Misc, USB) and normally last two of them support only slow charging. You can have charging speed of AC by increasing it (especially user while charging in car or using USB port)
    • Cpu governor optimizations
    • Gpu voltage, clock and stepcount interfaces (GPU Overclock/Undervolt)
    • Screen brightness curve settings with original panel gamma values. panel values unchanged, so you will get stock colors and will be able to use supercurio's voodoo display app when it is released. brightness modification will only change auto-brightness response.
    • BLN support both for Samsung and CM ROMs (you can use STweaks, Nstools or BLNControl app from the market to enable it)
    • Breathing or Blinking effect for BLN. (Make sure you don't enable blinking in any other BLN app) Use STweaks to select one of them.
    • Better touch sensitivity
    • Available CPU Governors: Pegasusq (default), Ondemand, Lulzactive, SmartassV2, Interactive and Conservative, Performance, Userspace, Powersave
    • CIFS as module
    • Available I/O schedulers: CFQ (default), noop, Deadline, SIO, V(R)
    • J4FS as module
    • ARM topology support (SCHED_MC)
    • Automatic EFS Backup
    • Lots of I/O tweaks and filesystem optimizations via some parts of thunderbolt scripts.
    • USB Mass Storage mode is working in CWM Touch Recovery and you can mount both internal and external sdcard as a disk drive
    • NTFS automounting for USB sticks. When you plug in an NTFS formatted USB flash it will be automatically mounted to /mnt/ntfs folder.
    • USB mouse and keyboard support
    • built-in profile support with default, battery and performance presets (you can change them in CWM Recovery). Even using everything default will save you a lot of battery juice.
    • Eargasm for headphone amplification (in STweaks) as free Voodoo Louder replacement
    • Almost everything is configurable such as scheduler features, hotplug thresholds, GPU frequencies, voltages, arm topology modes... and they are configurable via simple and free STweaks app which is embedded in the kernel and soon in Google Play & Opensource
    • Adjustable mDNIe settings
    • optional sharpness tweaks from hardcore
    • mDNIe negative effect toggle with home button (press it four times)
    • Touch gesture support by Tungstwenty. (http://xdaforums.com/showthread.php?t=1831254)

    troubleshooting

    siyahkernel-ics-wide1.png

    READ THESE FIRST

    • Never report any bugs to CM9/CM10 threads if you use it together with SiyahKernel
    • Do not ask questions to me directly. This is a common thread, not my personal inbox. Ask your questions in the thread and do not target them to anyone.
    • Do not expect answers to all your questions. There are some questions which nobody knows the answer of.
    • Do not forget that this is a development thread. There is another thread in general section for those who wants to discuss battery life and chats. If your post does not include a feature request, bug report or suggestion it should be posted to the other thread.
    • No ETA for new version. Even if I sometimes talk about release dates those may change and they change for some good reason or because of my real-life obligations.
    • Make use of "Search this Thread -> Advanced Search"
    • Never ever discuss anything deep-sleep related in this thread. I do not make modifications to prevent sleep and 99% of deep sleep problems are application/ROM related. discuss it in general section. I do not want any positive ("this kernel sleeps like a baby") or negative ("There is a big problem with deep sleep. Please fix it") messages in my development thread.
    • If you do not provide details about your configuration and settings nobody can help you or nobody will care about your problem/bug report. The problems without details (ROM, settings, preferably the version that the problem first happened or the one that you don't experience the problem) will be ignored.
    • Never ever report any SOD issues if you are undervolting/overclocking and make sure you attach last_kmsg log. If you don't know what it is report the problem to the other thread because one more post without any useful information on dev thread will help noone including yourself.


    FAQ:

    Q: I am having some random lockups with some apps
    A: try removing root by using STweaks app and restart.

    Q: What is the difference between STweaks and ExTweaks?
    A: Both have similar functionality. ExTweak is Xan's implementation of the UCI interface (which is designed by Xan and me with the helps of AndreiLux and implemented in the kernel as open scripts by me) and STweaks is mine. I was hoping Xan would release the sources of ExTweaks (without profile support) but he changed his mind and I decided to open STweaks. Soon they will have almost identical functionality, so you can use whichever you like.

    Q: Does this kernel work on XXXXXX-ROM?
    A: If the ROM is based on Samsung Stock ICS Rom LPQ or newer, it should. Otherwise, search the thread... If you cannot find any reference to that ROM, try the kernel. You won't lose anything by trying this kernel. Worst case scenario is to reflash your previous kernel or ROM. You can backup your previous kernel with Hellcat's k-tool from the market.

    Q: Where is CM9, MIUI or Samsung ROM versions?
    A: There is only one version. Both ROMs are supported with a single kernel image.

    Q: What is the best settings?
    A: It is the one you try yourself and like.

    Q: I have just lost 20-30% battery by just rebooting/flashing the kernel. Is it a bug?
    A: No. It happens because of our fuel gauge chip which doesn't require calibration goes crazy sometimes. It is not related with kernel or ROM. Just reset fuel gauge chip using STweaks app (or remove the battery and wait 3 minutes) and then charge your phone.

    Q: BLN doesn't work.
    A: you need to enable it in stweaks or BLN app. if you have more than one app to configure bln make sure all of them use the same settings.

    Q: BLN works in test mode but it doesn't work otherwise.
    A: if test mode works you should blame the apps. Stock messaging and email apps may not support BLN and in some other applications you may need to enable notifications. Either find another application or change your ROM.

    Q: Can I use breathing effect without using BLN?
    A: for now, breathing effect only works in BLN. There is no way of using it otherwise.

    Q: I need to disable and re-enable BLN in stweaks to get it working again. What is the problem?
    A: You may have another BLN related application (BLNapp, nstools, or a script) which disables BLN after stweaks apply the setting at early boot stage. you have to either uninstall that app or enable BLN in that app as well.

    closing the thread once again...

    I don't want to piss the mods again because this thread attracts too many people.
    most of them misinterpret the "this is a development thread" statement and use the thread for their self-development purposes.

    There are very few people who give useful feedback and suggestions and I talk to them over gtalk, email or PMs anyway.

    greetings :)
