I hear ya on that! It's reason enough for me to occasionally flash a Trinity kernel.
Can someone tell me what's the difference between the
P999-CM-Kernel-054-sv-stable.zip
and
P999-CM-Kernel-054-sv-lg-stable.zip
kernels? What difference does the Low Grade (lg) mean?

kernels? What difference does the Low Grade (lg) mean?
sv you can undervolt with sv stable. LG ver you cannot. Sv means stock voltage.

Installed faux 054 SV. Haven't played around with undervolting yet.
Do I have to use Pimp My CPU for undervolting?
Anyway, phone gets really hot at 1.5GHz. I'm still running tests.
At one point my G2X wouldn't turn on, I removed the battery (original OEM battery) and it was very hot.
There is one problem with faux kernel and it is with playing videos. I even tried this at only 1.1GHz max. If I play a video, any video, even for just one second, when I stop playing the video I can't scroll, swipe, or pinch-zoom anything. I can't pinch-zoom the video I'm playing either. This happens if I use MX Video Player the built-in video player, or any video player.
That means I can't scroll the desktop, the task bar, menus, nothing. The screen will only respond to a tap, nothing else. I have to press the power button to turn the screen off, then turn the screen back on again, and scrolling is enabled again. Is this a known bug?
This vaguely sounds like fauxs led bug. Does your player turn off button LEDs?

I use CPU master to undervolt.
The bug your encountering sounds like the lag bug when the soft key leds are off. By hitting the power button on/off it forces those back on?
That sound right?
Are you using any app to kill those lights? With Faux, you can't.

EE- I wanted to add in this is a known issue on Faux.
I use MX Player as well. Any app that kills the softkey led will cause severe screen/input lag if that app does not turn the lights on after it exits or you jump to home screen from app.
MX and Netflix apps both will do this for me if I exit the app by just pressing home. If I exit the app via back button or in app quit/exit button the lights come back and does not lag. Mazouts kernel fixes this starting with v205, but as I said, if control of the lights is handed back to system when app is done it won't happen. Try killing the app.
Also, it is known that some models of this phone hate faux and love trinity and vice versa. I am blessed to have a model that doesn't care. If you have issues with faux, try Trinity T15.
Also, yes, by default install Faux is OC to 1.5 and burns up the phone. I'm sure you've bumped it down by noe. My phone will handle 1480mhz, anything over is a bake fest.
I gotta go to work.
Do you use GTalk at all?

Thanks for everyone's help. It would have been nice if there was a bug list for faux.
Can I assume all faux-based kernels has this bug, like Mazout360's kernel?

Its been mentioned in this thread. Maybe Ill compile a bug list for my kernels thread. Digging through thia thread is a headache.
Mazout just used source, he has fixed that issue.
As long as you exit an app that kills those lights, you should be fine.
Try Trinity T15 if your not happy with Faux.
Or Maz's 205OC . Stay away from 218 , I've had nothing but issies.
Does the voice lag still exist?
Also, can you test wifi call on another hotspot at say a friends house?
Sent from my glorified LG pet rock™
Yeah, but when playing video I can't pinch-zoom or scroll, so Faux is out for me.
I had Trinity ELP, worked fine but camera quality could have been better. Or maybe it was because I was using an old CM7 nightly.
So it's between Trinity T15 and Maz 205OC. Trinity is older so I think I'll try Maz first.
From http://goo.im/devs/Mazout360/KernelP999 am I looking at Mazkrnl_0205GBOC.zip ?
Yes, I still get the voice lag. Free WiFi in my area so far blocks VoIP. A friend's house means messing with their router, maybe it comes down to the mismatched baseband?
UPDATE: Installed Mazkrnl_0205GBOC.zip. Nice and fast and smooth.
But I've lost haptic feedback on softkeys, no vibration, even though it's selected in Settings. Feels very strange.

Honestly the stock cm kernel is pretty decent. Not noticing bugs and I have an app that restarts my phone once a day so there isn't much slow down.

Did a test where I put my phone on pass-through of my router (DMZ) - still the voice lag on WiFi calling so it's not the router.
Also, tried it with an old RIL that matches the baseband v10f and I still get the voice lag.

Did you guys notice there was a new faux kernel version 55 on July 9th???

Faux buddy, any pointers on flags needed to compile with cross compiler v4.7 and above on 64 bit ubuntu would be greatly appreciated
-- The noob says:
This just in... my IQ has increased 50 points thanks to the g2x!
Can someone confirm whether button light off lag bug is still present?

161Here's a kernel build based on CM7 Kernel Source Tree
Special Shout out to DebauchedSloth for his pull requests and collaboration on this open source project
Just a statement regarding kernel source: The Kernel Source is of course covered under GPL version 2. Free software does NOT mean no work or time was spent working on it. I have donated a large sum of my free time to hack this kernel. If you use my modified kernel source in its entirety, I kindly ask you to send me a github pull request or PM whenever you find bugs or think you can help improve my kernel hack further. This way the entire community will truly benefit from the spirit of open source. Thank you
What is a Kernel? The Kernel is the Foundation in which everything else builds upon in any software system.
[Car Analogy]: Kernel is like the Engine, Electrical system and the Transmission to a car. The Library, Framework and the Apps [AKA ROM] are the body frame and the rest of the Car.
THIS KERNEL is BASED ON CM7 Source Code. So it is COMPATIBLE ONLY WITH CM7 Builds.
Please DO NOT use any task killers, they DO NOT improve performance nor battery life. They INTERFERE with your phone's stability (more crashes) and App compatibilities (Forced Close).
ZRAM (aka CompCache aka RAMZSwap)
ZRAM is an updated version formally known as CompCache and RAMZSwap. It was originally designed for 2.6.38.xx kernels, I have backported to our 2.6.35.xx kernel. ZRAM allows real-time compression of memory objects in RAM thus reducing memory pressure for the Linux kernel and can keep more apps in memory longer (more apps in RAM == better performance, less fetching from slower MMC or SDCard). Compression, however, is not Free. Some CPU cycles are required to do the compress/decompression, so there's a slight penalty for it. The original CompCache / RAMZSwap required a user space binary to control its behavior which adds additional penalty to performance, but the new version ZRAM eliminated the need for a separate dedicated daemon, thus reducing the overhead and increased performance from the old CompCache by 20%. Therefore, with the newer implementation of ZRAM interface, the performance penalty is almost negligible.
Joe's RCU (Optimized for Small SMP systems)
Joe Korty has created an RCU for small SMP systems (> 32 cores). His approach is to isolate all the Garbage Collection (GC, a slow time consuming but necessary processing) to a single core, thus allowing other cores to ONLY work on real required processing. This will allow the additional cores to complete their assigned tasks as fast as possible (not bogged down by GC) then immediately go back to a suspended state (saving battery).
Fast No Hz RCU (Optimized for SMP operations)
Fast NoHz is an optimized version of the traditional Tree RCU. Many new kernels are using the Tickless NoHz design. This RCU is tailored and designed to work with the new NoHz kernel system.
Brain F*ck Scheduler - (BFS)
This scheduler is designed to be simple and speedy tailor specifically for user interface type systems such as desktop/smart phone devices where user interaction is MORE important than serving 1 million web requests (CFS, the default scheduler) at the same time (think of nimble desktop workstations vs large corporate servers).
SLQB - (SLAB allocator with Queue)
This memory allocator is designed for small number of CPUs system (such as desktop or smart phone devices). This allocator is design to be simple and it is optimized for using order-0 pages as much as possible (order-0 pages are the simplest therefore quickest type of memory in a Linux system to allocate). Not all kernels are using SLQB including CM7 main line...
Fair Budget Queue (BFQ I/O scheduler)
This I/O scheduler is an improvement on top of Completely Fair Queue (CFQ). CFQ is fair in terms of time but not in terms of throughput / bandwidth, so BFQ make sure that both time and throughput / bandwidth are balanced across all requests.
THIS IS ONLY FOR THOSE WHO ARE WILLING to FLASH THIS ON HIS/HER OWN PHONE... IF YOU ARE NOT COMFORTABLE WITH THIS YOU SHOULD NOT FLASH THIS.
For those who decide to flash, please post the results and/or issues here
