[Galaxy S II Q&A, Help & Troubleshooting] droidphile:
Partial wakelocks are caused in userspace. (by your user apps and system apps).

Kernel wakelocks are wakelocks in kernel space which could be suspend-wakelocks and idle-wakelocks. (found in /proc/wakelocks)

We can not control kernel wakelocks, but we can reduce partial wakelocks caused by apps by tuning their settings; and thus prolong deep-sleep.

[Galaxy S II Q&A, Help & Troubleshooting] droidphile:
1) Are you sure these frequencies worked for you before? It's recommended to use the default frequencies as the available set. With options to set first frequency to 1696 instead of 1600 or last frequency to 25 instead of 100mhz.

2) Try increasing your voltages.

3) Reduce loadh to 70 from 80 and reduce loadl to 30. And see if it make any difference. Very high second-core-kick-in threshold (80 in your script) has caused me a freeze too in the past.

4) Even screen-off second core thresholds seems 'scary'. Make it something like 60 & 95 (instead of 99 & 100)

5) Try increasing voltage for gpu@400mhz to 1200000

6) 12000 sampling rate may be too low for your governor. Try increasing it to 50000 or so.

7) Set your awake governor once before the loop also, for safety reasons.

8) Last but not least, make sure your script doesn't have any syntax errors.

For not-booting issue, move script out of init.d.

Boot into recovery.

adb shell

mount -o remount,rw /dev/block/mmcblk0p9 /system [if /system is not mounted as RW already]

mv /system/etc/init.d/script-name /system/etc

mv

exit

Reboot and find your script in /etc.

Gentlemen

all the work done to this kernal is simply amazing

95% stable ( very random and rare BSoD ) ... excellent results that put a big smile on my face ^_^

recently tho been flashing all the beta's and into 2.3

cant seem to find a way to make my settings stick after reboot... it doesn't bother me at all for now ( will search for an answer after writing this up ) but what has come to my attention is charging

having battery monitor widget installed and keeping an eye on how much the phone sucks up from the charger/usb... varying numbers but nowhere around what i have set in voltage control app ...

currently have charging current set @

charger : 900mA

Misc : 900mA

Usb : 500mA

on charger (both sammy original home charger and 1mA universal car charger) the widget shows +495mA and +329mA and on Usb shows in the 130-140mA range

what am i doing wrong or where should i be looking at to have my settings stick for charging?

I/O Sched @ sio

governor @ conservative

mhz from 100-800

voltages @ 100mhz-850mV , 200-850 , 500-850 , 800-975 running strong and stable

gpu voltages 160Mhz - 850mV and 267 - 900

running wanam rom v6.0 , will update later on to v6.2

he got tweaks for ondemand and wondering which tweaks will stick... the roms or the kernals?

and thanx for any info in advance

Your awake and sleep governors are probably conflicting. (conservative & lulzactive).

Why do you wanna use lulzactive as sleep governor anyway? It locks screen off frequency to 150mhz in your case. Instead you can use conservative 150-150 as screen-off.

I'm having quite a few issues after trying the 2.4 kernel:

1. Phone doesn't wake up from screen-off, slow wake up if lucky. (Tried all cpu profiles)

2. Phone turn off itself / reboot itself

I've come from stock kernel running CM7.1 nightly 116. Had to revert back after this. Had all caches wiped after flashing the kernel.

On that note, please also state in BOLD at the download page stating that the CWM only supports external SD card (started to happen since 2.2 beta 5 i think). Hate to use revert using Odin.

Also, any chance to upgrade CWM to 5.5?

■some stability fixes (at least it did not crash on my phone for the last two days)

■BFQv3 & it is set as default I/O Scheduler

■fixed NTFS auto-mounting

■default governor is set to conservative@100-1200MHz

Font smothing is turned off on lock

I love this kernel. I have tried many and this is the only one that has "Android OS" under leash in terms of battery usage.

there is one problem however, it seems like after a reboot as soon as I lock the phone the font smoothing is disabled and it makes the text really ugly.

I tried taking a screen shot of some text, when I view the screenshot on the phone it looks terrible, but when I transferred the image to my computer it looks find, so maybe it's not the font smoothing but rather something with the graphics in general.

is there a way to fix this issue, I search the dev thread and there are some references to it but I can't find a mention of a fix.

So I've been wondering, why do people like governors with screen-off profiles?

I can't stand having to wait 5+ seconds just to be able to do anything after I turn the screen on.
[Galaxy S II Q&A, Help & Troubleshooting] droidphile:
All governors with in-built-screenoff profiles does not take seconds to wake up. It depends on your scaling minimum frequency as well.

If you use lulzactive and set scaling minimum frequency to 25 mhz, then frequency will be locked to 25mhz during screen off and it might take a second or two to wake up. If you use smartassV2 or ondemandx, the waking-up is almost instantaneous.

Since, the whole idea of using a governor with screen-off profile or a governor and a user-set screen off profile is to make sure device doesn't use higher frequencies during music play/downloads/time between wakelocks & screen-turning-off automatically, etc, couple of seconds delay can be a trade-off.
