Motley, I know you said that the debug flag for pm is not set, but it doesn't default on if commented out of your make file?

No, for a Linux kernel, options to be compiled into the kernel will either be =y or modules will be =m. When you turn off an option when running make menuconfig, it will comment it out in the configdef file.

Good news! I have a fix for the lock screen! Doing some testing now. It was the touchscreen driver like I thought. The Melfas driver automatically was downgrading the firmware on every boot with built-in firmware compiled into the kernel (not a .bin file on disk). I have now eliminated the firmware downgrade by toggling some available switches they had available and just allow the firmware to be whatever it is already on your tablet. The firmware seems to only stay resident until you reboot and then it reverts back to the firmware that was already on the tablet. This may explain the wacky differences between tablets if they were on different firmwares.

Edit: new release see OP

Version 1.0h changes (beta 1):
-Touchscreen lag appears to be fixed! Let me know how it works for you.
-UV bug fix (experimental, still in testing)
-Governor fixes, SetCPU seems to set properly on boot now.

v1h does fix the lock screen lag for me, well done ,thank you !
for setcpu function, i still cannot get interactive scaling work when boot,
i set cpu at 1.4ghz interactive mode before reboot, it works normally,
however, after reboot, i check the clock in setcpu, it locks at 1.0ghz, not well scaling, and i do check "set on boot" option in setcpu.
but if i set to ondemand mode, it works well even after reboot...

Thanks for the lessons and the fix!

This was really the only thing keeping me from full timing this rom.

You just revitalized this community! And probably helped Samsung sell ozens more 8.9s

Sweet, UV control. Time to test things out, and how far you can UV a Tegra 2.

EDIT: Apparently, UV control works now. I set a -200mV UV on the device at 1000MHz, and it hung up after ~10 seconds.
EDIT2: My Tab is happy at 1000MHz@-175mV. Thanks motley!

I'm running stock, used CPU Master Free to set Conservative 1504 Max, 216 Min, ZERO lag here. Great job!

I'll be adding & recommending your work in my epinions.com review of the Galaxy Tab 8.9

P.S. With all these settings, battery drain in standby is less than 1%/hr.
