Hi,

Not sure what you mean by 'kernel management apps' but I don't have any of those RAM booster application in case you referring to those.
If you don't know what a kernel management app is, maybe you should stop flashing things and do a little more research first. Just my 2 cents.

Any idea why dt2w always reverts to halfscreen even though I set it to full? This happens without rebooting, after the phone has been on the charger...

Yeas actually... Nexus 6 panel actually is to blame for this. The code written for the dt2w is set this way to fallback to halfscreen even if numerically set to 2 (full screen)

Will still function as it should

Hello all,

I recently started using Blackbird for the Nexus 6 and I've been getting some strange errors, that I'd like some type of help with or at least if you can point me in the right direction.

Basically what happens is that seemingly randomly, my cell reboots itself, it does it almost every day and then after a few days it reboots and gets stuck at the boot logo.

I'm really new to taking logs, please let me know if you need me to do it a specific way or anything you need.
Any assistance would really be appreciated.
Thank you.

I use Nitrogen for the Rom, Open GApps - Full, Blackbird for the Kernel, and Viper4Arise - Swansong for Audio, and it was from a clean flash.

*I already posted in the rom thread, and they advised it is kernel related, so that brought me here

I looked through your logs and I really didn't see any kernel errors... I did however see slot of errors caused from ROM / device tree side... I ha e noticed lately as well alot of the people who ARE having issues are with Nitrogen ROM only too.

Interesting, I posted my blurb there and the logs, but was directed here since I use your kernel.
Did you see why it randomly reboots? Or anything I can bring to the Rom thread.
Thanks a lot Reventech

Alot of the errors I'm seeing are sensor and media related errors. The log doesn't show when reboots occur and is best to grab it while it immediately after or during the occurance.. if you can make it repeat and Target or trigger what causes it and log it then we'd have more success in figuring it out. But yea the log you sent is really riddled with alot of ROM related errors

What you were told more accurately is that since you flashed a third party kernel the ROM developer cannot help you. He's only going to support clean flash and gapps only. No one else seems to be having this issue and as I am running nitrogen and Blackbird without these problems there must be something with your device or setup.

I have to agree with you; I have been running that combo for some time and have never had any issues.

That gives me a direction, the next time it happens I'll try and capture a log of it right away.

Hey REV3NT3CH,

Love the kernel. Been using it a while. I just updated to the latest version and was wondering if someone could explain AutoSMP's hotplug settings "downrate limit" and "uprate limit"? Can't seem to find the info anywhere.

I'm used to using state helper.

Hey REV3NT3CH,

So I reposted my issue on Nitrogen's thread and was advised to reflash the rom with stock kernel.
Before trying that, I'd like to know if you notice anything that might explain the reboots in this latest logcat, I captured it right after the lastest random reboot.

Thanks again for the assistance (I'd really like to keep using your kernel)

i'm mostly sure you have that correct- i have the same problem the other person is describing and it too was also on the nitrogen, with the time frame being after the 7.1.1 release
right now, i'm trying my setup (bb kernel, magisk) on resurrection remix (neo) and running the phone at max everything to see if i can cause the same problems from nitrogen, but so far i have nothing
i'll try to get a log once i've managed to get the weird reboot/settings reset crash

    Notes::

    For maximum stability. Before I flash each update of my kernel, I go to settings>apps>Kernel-AduitorMod>storage and wipe the cache and data for it for a fresh new setup. I do this because when and if i do add or remove a feature you set on boot and its not there. it may cause conflict.

    Starting with Version 1.9. The current rom you're on must have the latest google security patches as of august 2016 in order for wifi to work properly.

    If you come across a bug or issue please do not spam the thread. either pm me or reach me on hangouts or g+ by rev3nt3ch@gmail.com

    Frequently Asked Questions:

    Q: What is the difference between Upstream and the 3.10.40 version?

    A: Upstream (currently 3.10.107) has the latest kernel patches from the Linux kernel upstream updates from kernel.org where as the 3.10.40 is where Google has left the kernel at stock for the n6. Basically it's just updates from Linux Mainline that have fixed issues found in their code. For those that also don't know, Android is a mobile form of Linux and uses the Linux kernel.

    Q: Whats your current setup using the modded kernel aduitor from yoinx?

    A: Darkness governor
    CPU Min Frequency is at 300mhz
    CPU Max Frequency is at 2496mhz
    GPU max frequency is at 600mhz
    Hotplug is set to AutoSMP with 4 Max cores online and 2 Min cores online
    Screen Color Profile is set to Deep Black Colorful
    Sounds Volume Gain is set to 4
    DoubleTap2Wake is set to Fullscreen
    Vibration is set to 50%
    TCP is set to Sociopath

    Everything else i leave AS IS.
