Was this when connected to a charger?

Which 2/18 build? A or B? Were you on 15C before?

crash-to-LPM is pissing me off - it's damn near impossible to get a log.

I'm going to look into maybe putting something in the initramfs to dump last_kmsg in LPM.

I want to say that 2/15c is awesome on my rom so far. 2/18b was a step backwards. I know the changes aren't great and I don't understand why the big difference but it is. Finally something better then 12/8/11.
Take it for what it is.....

PLEASE compare 18A to 18B!!!!!! The ability to do so is the whole point of releasing kernels with one patch per release. Also provide more details as to the circumstances where it performs more poorly power-wise.

I'm much more inclined to investigate/rework/revert the patch in 18A than 18B. The 18B patch is from Linux mainline, which means - it's gonna be in ICS whether you like it or not.

Red: Can you confirm again that 26 was the one problematic for you? I've already decided to revert that patch for now and investigate other solutions for Nizda1's issue (if he even has it again, ashmem may have been a red herring) because unlike shoman94, you narrowed it down exactly to a specific patch and you were able to see a night-and-day significant difference. (I don't think I've seen any feedback on 18A from shoman.)

Entropy,
We can add even XWKL1 base to bug list; in idle state, XWKL1 base drains 10%/ hour on my work wifi with AOS topping >67% with lots of wlan_rx wake locks.

BBS log: http://db.tt/8HJk20yv
About 28k wakelocks in an hour!
I looked for wake_lock_destroyed in dmesg but didn't find it heavily populated with those. What else should I look for in it?

I did not get that many wakelocks at work, but still heavier than usual battery drain.
logcat, dmesg log (with debug_mask = 35): http://db.tt/LwMkZVEb
BBS log: http://db.tt/w9iS8XRX
1698 wakelocks in 38 mins.

At home, I have D-Link DIR-655 router and Microcell.

I will be testing 02/26 overnight. Tomorrow, I will switch back to 02/15-C and post similar logs.
Bump!
Probably this post was missed. It shows that 02/26 was a problem for me.

BBS log of 02/26 overnight with Wi-Fi on.
Staying on 02/26 overnight was a disaster too. Weird.. if I turn off Wi-Fi, I get deleted wake locks and if I keep Wi-Fi on during night, I get wlan_rx wake locks (because of the bug in 2.3.6). Then what's the point of turning off Wi-Fi? Above logs are for 2/26 on SHOstock 1.9.2.

Now I am testing a different ROM on 2/15-C

I believe it was 2/18b (confirm definitely 2/18b) since the kernel was actually dated 2/18. It was charging via PC USB rather than the standalone adapter. I had skipped 2/15c coming from build 1/30/12.

Ya let me go back through both 2/18's and then 26. Give me some time though as I want my phone to use then for a bit to be double sure.

You haven't seen any feedback on 18a yet because I haven't used it. I can only run one kernel at a time and I need a full day so I can test it. I was planning on flashing 18a tonight.
So again I will be flashing 18a tonight and report at the end of the day tomorrow.
Between 15c and 18b I haven't had any problems but 15c just performed a touch better and was quite a bit better on battery life.
