Sgs kernel flasher will only work if rooted :(

Looks like I'm good to go then ;)

I downloaded the latest kernel(10/06), but when I extracted the tar file, it gave me zImage file that is a document? Shouldn't it be an exe file ?

I really do wish you added oc as I love to do so, but could you please add Smartass governor?
I'll look into it, but it's pretty low on my priorities list. Most of the wacky governors don't provide enough benefits to justify the risks. Nearly every time I've seen someone release a kernel with a custom governor on the Infuse it was broken and did all sorts of strange things. Again, stability is my #1 goal.

Looks to be a nice update. Sgs kernel flasher should work too, right?

To my knowledge, I've seen reports that SGS Kernel Flasher won't work on GSIIs.

My guess is that it hasn't been updated to account for the fact that the GSII has moved away from Samsung's proprietary STL/BML partitioning crap.

You can achieve the same results using ADB, or even a terminal emulator session:
Code:
adb push zImage /sdcard/zImage
dd if=/sdcard/zImage of=/dev/block/mmcblk0p5

Yeah, just tried SGS kernel flasher, it's not supported yet. Any reason im getting a document file extracting latest kernel tar file?

I just tried downloading and extracting both 10/06 tars to see if I accidentally put something extra into them - both contain only zImage and no other files.

Yeah, I'm getting only the zImage, but the file itselft is not a Unix executable file. It extracts a zImage document file.

Observation, while pluged into charge the device never goes into deep sleep.
Not sure if this is similar on other kernels or working as intended

Thanks

I have tested the kernel released yesterday and my battery drain was really bad...reverted to 10/04's kernel and my problems went away. And my two cents on over clocking...I would also like to see a kernel with OC'ing, maybe have one with and one without it.

I overclocked on my infuse and my international galaxy S II and never had a single probelm. On my Droid Charge I have had problems with the 1.6ghz clock and undervolting so I just leave it alone. Luck of the draw I suppose. I still say its a good suggestion to do one with the OC option and one without it. I dont know how hard it is to add the feature but I will look into it. I can use kernels from the i9100 for reference I guess, it all depends how bored I get this weekend.

It doesn't need to be executable... There's no point in trying to execute it. For whatever reason, permissions were set to +x in the 10/04 release and not in 10/06. +x permissions don't matter when you're flashing in Heimdall and shouldn't for Odin either.

That's normal on every Android device in existence. An AC or USB connection holds a partial wakelock.

Need more details. Try the kernel again, get some statistics in BetterBatteryStats and Settings->About Phone->Battery Usage - I cannot reproduce your problem and therefore cannot debug it. The conservative governor tweaks in the "experimental" 10/06 version might trade some battery for performance but it shouldn't be significant. Were you running the exp release or the non-exp release? If you were running exp, do an A/B comparison of the non-exp and exp releases please.

I might pull codeworkx's OC code into a separate branch and release from that, but I will not accept bug reports regarding stability unless someone is running a non-overclock release.

I just want to say thanks for replying to literally everyone on this thread, I dont see that very often so kudos! But yes I was using the non exp release of the kernel. I am happy with the 10/04 kernel but I will more than likely give it another go once my battery hits 100% again and start looking into the BBS to give feedback. When using BBS what info are you looking for? I have never really used it because if I have a problem I just revert to what was working. I would like to give you exact feedback if I decide to try it again.

Look for anything unusual in Wakelocks/Since Charged.

Also try the following:
Install CPU Spy
Once you take the phone off the charger, Reset Timers in CPU Spy
Do whatever
Open CPU Spy and look at the frequency statistics, including Deep Sleep.

10/7/11 update

Small update here - /system/etc/init.d support in initramfs, that's all

Also attached an example script that changes the CPU frequency governor to ondemand

Next up - another attempt at ramconsole. I'm nervous about implementing undervolting, OC, or anything extreme without working ramconsole (/proc/last_kmsg). :(

Time for pain and suffering for me - committed codeworkx's overclock/undervolt patch.

DO NOT report any stability bugs unless you are running the default voltages and stock clocks.

It's the 10/7 "doom" release.

Pulled the 10/6 experimental release since the only difference between it and 10/7 is init.d support, which should be perfectly safe from any regressions.
