I think there may be issues with the Wi-Fi drivers; I flashed the latest kernel this weekend and while Wi-Fi worked fine, Wi-Fi calling (the bundled TMo app) was stuck at "Enabling ...". I went into the apps advanced settings to check the error log and it alternated between ISP errors and carrier errors; I went to ping the network (also in the advanced panel) and the server was listed either as 'NULL' or 'INVALID'.

I cleared cache and data of the app, nothing; I cleared cache and dalvik, nothing; I reflashed CM7 keeping without reflashing this kernel and it worked fine; when I then reflashed this kernel, it quit working again.
[G2 and Desire Z Android Development] Neejay:
I don't know man...I've flashed the latest nightly, then flashed this kernel, and I've been using Wifi with no problems at all.

EDIT: wifi AND wifi calling.
[G2 and Desire Z Android Development] pershoot:
nothing wrong with wifi calling from where i am and the current wifi module. i am on it constantly (and have been since the 3rd (when the wifi module was refreshed)).

post logs if you feel it is due to the wifi module and/or revert back to the previous wifi module (if you still have it), to test.

check with tmo as well to see of any issues in your area.
[G2 and Desire Z Android Development] OriginalGabriel:
Yeah, something is up ... To make sure it wasn't my works router I redownloaded (via Wi-Fi on my home network) and reflashed your kernel when I got home and, after rebooting, I only saw my saved networks as out of range (even my home network that I was just a few feet from), all of my neighbors networks (which usually show up) weren't showing. I deleted my home network and tried to scan for it, but nothing.

I'm currently redownloading CM7 #63 (what I've been running since I ran into walls with the next few nightlies) to reflash and double-double-check that but, what logs would help you out and when should I run them?

If it helps, I'm on a HTC Vision/T-Mobile G-2 running the stock radio and CM7 #63.
[G2 and Desire Z Android Development] pershoot:
i would need the logcat/dmesg.
[G2 and Desire Z Android Development] OriginalGabriel:
Sorry, I've never had to deal with either much; logcat I know, but how would I get the dmesg and when should I start them (I'm assuming before turning on Wi-Fi)?
[G2 and Desire Z Android Development] pershoot:
I can reproduce this in a certain scenario. Will investigate when I get back from IO and send a test.
[G2 and Desire Z Android Development] OriginalGabriel:
If you're referring to my Wi-Fi issue, it was a constent issue with CM7 #63 and no amout of reboots, clearing cache, etc. would fix it; on #65 it only happened once (I also couldn't connect to/see any carrier network that time) and a reboot fixed it.

Yes, you can. Just installed with no problems.

0513 kernel ok?
[G2 and Desire Z Android Development] G1ForFun:
All good here. Wifi and all.
[G2 and Desire Z Android Development] heybobitsme:
Yep. Just flashed a little while ago on CM nightly 75 and had a GPS issue, but an extra reboot fixed it. Everything works.

On a side note, I can't wait for the G2 Gingerbread to be officially released so we can bug HTC for kernel source.
[G2 and Desire Z Android Development] imperfection:
I love this kernel. I am using it (not overclocked) with CM 7.0.2 and am at 13 hours 55 min with 51% left. I had a phone conversation for 1 hour and my display was on 1 hour 30 minutes with me using the browser, heavily texting, and using Twicca. I left wifi on all day and was also at my bf's where we get very poor signal (1 bar of edge by the window) for like 6 hours. I'm impressed.
[G2 and Desire Z Android Development] dyndragon:
working great, but still sometimes get reboots when rotating home screen. Not likely to be kernel related. If it gets worse I'll check dmsg
[G2 and Desire Z Android Development] j.youngberg:
I'm having issues with waking screen up from sleep with any frequency above 1.2GHz. When I tap the wake button the soft buttons illumintate but that's about. I'll have to push the button several times for it to finally come one. I've tried messing around with on/off animations and animation speeds but nothing has helped so far. Any advice?

Thanks
[G2 and Desire Z Android Development] G1ForFun:
Known issue....the only work around is to set your brightness above 50%.
[G2 and Desire Z Android Development] OriginalGabriel:
Pershoot, will this get bumped up to the new 2.6.35.x kernel anytime soon? Folks are warning against any other kernel with the latest CM7 nightly.
[G2 and Desire Z Android Development] j.youngberg:
Thanks. I'll give it a shot.
[G2 and Desire Z Android Development] pershoot:
I-youngberg, ill look in to it. For nkw pls use the workaround.

Dyndragon, doesn't sound like the kernel.

Post logs if you feel it is kernel related.
[G2 and Desire Z Android Development] j.youngberg:
Using the workaround right now. I have the CPU set at 1400MHz and the brightness set at 55% and its working great.

[G2 and Desire Z Android Development] j.youngberg:
Also, curious to know if Pershoot has plans to update the kernel to .35. Thanks.
[G2 and Desire Z Android Development] xsteven77x:
I'm sure he does have plans to update it, just a matter of time.
[G2 and Desire Z Android Development] j.youngberg:
This is the first time that I have been running this kernel for a whole day. Overnight my battery dropped like a rock from 60% to 20%. After looking at battery usage the top three items were cell standby,phone idle and wifi. I love this kernel but I need my battery life to last more than 14 hours. I was getting about 36 hours on vanilla CM.

Sent from my HTC G2
[G2 and Desire Z Android Development] pershoot:
Battery life is subjective and is determined per use case.

Sometimes I get 2 days, other times maybe a day and then other times could be 2.5 days and maybe as low as half a day.

It depends on low signal, how much you used the phone, bg apps, etc.

Some good rules to abide by to get the most out of your battery:

Be mindful of overclocking and its drain

Try to be on wifi as much as possible

Keep your brightness a bit low

Check your bg apps

Monitor your actual useage patterns.

Also keep in mind, that the battery tech has not changed in quite some time.
[G2 and Desire Z Android Development] j.youngberg:
My phone usage was less than normal yesterday. Also, my phone signal was a lot better than normal. Brightness was set around 55%. Anything less causes wake issues. I'm overclocked to 1.4 with pershoots. At 1.2 with stock CM I was getting about 36 hours.

Sent from my HTC G2
[G2 and Desire Z Android Development] pershoot:
You just answered your own question.

You doubled the overclocked and increased brightness.
[G2 and Desire Z Android Development] pershoot:
ill try to look in to the brightness thing when oc'd very high, tonight.

i believe it to be a race condition of some sort with the updated light sensor driver/logic im using.
[G2 and Desire Z Android Development] j.youngberg:
Awesome! Thank you. I really appreciate it.

I'm going to bump the OC back down to 1.2 for the day and also reduce the brightness as much as possible. I've also wiped and refreshed battery stats. I'll report back with my new findings.

Sent from my HTC G2
[G2 and Desire Z Android Development] dyndragon:
you are correct, it was not a kernel problem.

What are your thoughts about the GPS weirdness that people have been reporting with the G2 and CM7? GPS never getting lock, or GPS signal loss while navigating, and needing to dis/enable GPS in order get GPS lock back, etc... Just trying to rule out the kernel as being a possible root cause (in general, not meaning that your kernel is causing it).

I've tried formating the EFS partition with the GPS data, uninstalling GPS status (suggested that it might be corrupting the EFS data), still no good. Changed radios, reflashed ROM....
[G2 and Desire Z Android Development] pershoot:
dunno, GPS locks within seconds for me and stays.

i do recall someone having a similar issue, and they flashed some radio to get it back in working order.
[G2 and Desire Z Android Development] xsteven77x:
By the way its not a suggestion. Not sure if its the efs data or what but gps toolbox without a doubt breaks our phones if you let it download the XTRA data.
[G2 and Desire Z Android Development] dyndragon:
Right, but this is only if the GPS status app is run, correct? Or even if it is installed, it will autodownload the XTRA data regardless of user input?

Not going to hijack thread. Direct any more GPS discussion here:

Question

Thanks for your work Pershoot. Looking forward to trying this kernel. But can I flash the kernel without flashing the lib modules? Or is that not recommended?
[G2 and Desire Z Android Development] Aumkar:
Dont look at the Gingerbread battery use graph. That doesn't really show anything. Use Spare Parts with CPU Spy to see what frequencies your phone is at most of the time, and what's keep it awake ( ie partial wake usage )

Thats interesting. I usually get 40-50 hours. But then again, I'm on 2G most of the time, because I haven't activated my 3G plan yet.

But I think Wifi on all the time is a bad idea :S. Unless you use bandwidth-heavy applications on your phone. I use Twitter, Gmail, Whatsapp, and the like and I put wifi on when I'm in bed and need to stream and stuff. Or I need to use Wifi File Explorer to transfer stuff to and from my phone. Or if I'm not at home, but in a known wifi network area.

As for brightness, I leave it on automatic, which will no doubt increase the sensor usage, but is convenient and I don't need to keep switching the brightness between places.

However, I do monitor my usage, and ever since I got my G2, a month ago or so, with an 1800mah, I can afford to run everything that polls with 15 minutes intervals and stuff and not have to worry about wifi being on all the time and whatnot.
[G2 and Desire Z Android Development] mrbusiness85:
I just flashed this kernel to my G2 with the Virtuous-Fusion-Vision-v1.0.0 Sense 3.0 ROM and it runs like greased lightning now. NICE KERNEL dude. Nearly doubled my LinPack score from 27 MFLOPS to 50 MFLOPS.

[G2 and Desire Z Android Development] dyndragon:
Thanks for the confirmation. I have a hunch it might be something to do with the light sensor, to be honest. I'll play around with it. It always seems to happen on wake when it tries to brighten the display up depending on the ambient light.
[G2 and Desire Z Android Development] pershoot:

ill work on getting the older driver back, which 'should' alleviate the race condition on high OC and brightness.

I seem to have an odd issue and I don't know if I'm the only one getting it. When I use setCPU to overclock to 1.228ghz and leave setCPU then go back the max clock is set down to 998mhz. I flashed an older version of your kernel and the issue is gone. This is on MIUI 1.5.13.
[G2 and Desire Z Android Development] Wifiguy:
1.228GHz works fine for me in setCPU with the new kernel.

Try as I might I cannot reproduce your problem, I'm on CM7 stable.

Maybe it's a MIUI problem.

Guess you thought I was being rude? I apologize to anyone who took it that way. Its pretty obvious that cm is what most (not saying all) use this kernel with. Since the cm7 switched to the new kernel this thread has died off significantly.

[G2 and Desire Z Android Development] pershoot:
what makes you think it died off? there are a handful of people that use nightlies. more so, final releases, more so, etc. roms. etc.,etc.

take a look at the view count, and that will give you an indication.

I tested the latest .41 on MIUI 1.5.20 and didn't have any issues with it what so ever, so I think you're safe in using it. I just went back to Pyro's kernel because the combination is amazing on my phone. It may have just been your flash.

[G2 and Desire Z Android Development] Aumkar:
Hm.. I'm not sure if this is a kernel issue or not.. but I've noticed over the past few days that when I use my griffin wall charger ( I usually use my PC, but I'm moving, so I took it apart for the packers ), my phone gets unnecessarily hot. Its not doing anything, and Spare Parts and the Battery Usage screen don't help. Doesn't change even after a reboot.

I don't want my phone to get blazing hot while charging. I've reinstalled both my CM7 and the latest kernel. Not sure what exactly the problem is.

Running CM7.0.3 Stable with the latest 5/24 kernel.
[G2 and Desire Z Android Development] OriginalGabriel:
From my understanding, its normal for the batteries to heat up during a charge; a reboot wouldn't change the temp, you should see it gradually decline in temp after unplugging it though
[G2 and Desire Z Android Development] Aumkar:
It went to 39.8C =/. My room temp is at 24C with the A/C on.

Also, I seem to be getting terrible battery life with the past two kernels. With my 1800mAh battery, I used to get around 40+ hours with twitter autosyncing, wifi off, EDGE on and all that jazz with an hour of phone calls and plenty of texts and whatsapp usage.

Now I'm barely getting 24 hours.

Edit --

Also, my Wifi location was always on, even when I had 40+ hours and with this new terrible battery life. I've tried reinstalling the kernel, reinstalling cm7, charging to full, wiping battery stats and trying again. But no go. Also included is an hour of music everyday with both lengths of battery life.

[G2 and Desire Z Android Development] Aumkar:
Well for some reason, the .35 kernel, whichever one I've tested has shown lower performance ( benchmark-wise of course, but I dont care for numbers ) but also makes the UI slightly choppy and stuff.

I tested the Umarokernel on the latest nightly ( which brings me to why isn't the buildbot working? ) and it just wasn't as smooth as 7.0.3 with pershoot's kernel. Even 3D wasn't smooth at all.
[G2 and Desire Z Android Development] G1ForFun:
