I want to report several BSODs. It's for the first time with that kernel , have been using and testing nearly every new revision of the M-kernel, not a single problem till version 33. Now it always happen during deep sleep, had several for the past 24 hours. When i use it it's snappy and all, but when it goes to sleep it hangs. Than the strange thing is , after reboot, the device hangs at the Google logo and i need to restart it once more to start properly.

I have no idea how to post a log file of the events , but if someone point me , I will gladly do it to help for solving a possible problem.

The ROM is CM 10.1 M1

Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a33

I love this kernel but it take time to boot or sometimes it stuck on Google logo and to fix that is to erase cache from fastboot so I revert back to bricked .but I miss the smoothness and the battery usage with this kernel

can somebody tell how much time does the ROM boot with this kernel ? Is anybody have this issue ? If so ? Have anybody of u told the developer about that ?

Please don't ignore this post
[Nexus 7 Android Development] adstraylight:
Once again, make sure you're bootloader is up to date - v4.13. If you're running 3.41 it can take what feels like a very long time, but it will eventually boot. At least that's my experience.

Btw, posts are never ignored, people sometimes just have nothing to say, or the subject has already been covered.

Well, when I was doing my bootloader experiments 3.34 booted as fast as 4.13, but that was with a much earlier M-kernel version, so I hope it works for you - would be interesting to see, please report back :)

In any case the advice still holds, as at least you can discount the bootloader as the source of the problem by flashing 4.13..

Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a33

I'm having problem with BSOD too. Yesterday, before sleep I put my n7 to charge up and this morning when I was to use my tablet, there was only black screen and suddenly rebooted. After that I have checked in trickster mod and all my custom values were reset to default a33 values. Besides that, I think that metallice could check lowmemorykiller code because it's making close apps without any fc advice (like android keyboard or Google reader).

Right now I'm on my tablet, so I couldn't upload my last_ksmg or my logcat, later I'm going to upload from my PC.

PD: I'm on 4.13 bootloader too, so I don't think that have any relationship with problems on this a33 version.

My experience is that PA with just gapps and A33 boots normally, but adding Ac!d or Louder+ causes long hangs. Louder+ results in an infinite hang at the Google screen, with Ac!d it boots after about 5 minutes. Again, as I said, flashing just PA, gapps, and A33 my N7 boots normally.

Sorry but I have to step in with a clarification, 'cause if I didn't know better I'd be confused :

Once you have a SOD, either force a reboot or alow the device to reboot itself, then grab the last_kmsg. If you try to get it via adb while still in a state of SOD, you will fail(edit: to get any information related to your SOD), the same if you reboot more than once.

SODs

It does seem odd that for some it's a rarety (or hasn't happened at all), while for others it's a very common if not regular occurrence. To me this suggests that it is something possibly related to hardware tolerance (though to what, I've no idea). My N7 is from what I think is quite early in the production run, as I bought it pretty much at release. So I'm wondering, as I seem to remember there being a hardware update coinciding with the release of JB 4.1.2, if its just older devices that are getting SODs?

Mine is from batch C60 btw - 8Gb model.
[Nexus 7 Android Development] Leonhan:
Well its probably a fault with the rom they are using or it could also be hardware related as I remember having Metallice change some voltage. Been running fine with no SODs thus far. As with battery usage, I used wifi for an hr and have it deepsleep for 12hrs and the battery consumed was only 5%. That's really solid for me.

Re: [KERNEL][3G+WIFI][4.2.1] M-Kernel - a33

I'm having trouble upgrading my boatloader. Extracting the img file from the upper post didn't help because I don't have a pc at the moment. So I searched xda and found a flashable bootloader zip file. Unfortunately, even though flashing seems to go through, my bootloader continues to stay on 3.41

What can I do?
[Nexus 7 Android Development] adstraylight:
AFAIK the only way to update the bootloader without a PC is via flashable zip - sorry.

EDIT: I just read through this thread: http://xdaforums.com/showthread.php?t=1989319 - which I'm guessing is the one you found, and it seems you're not alone. There are a couple of possibilities - 1. your ROM (stock?) prevents the update via recovery somehow (there was one user who got it to stick after changing ROM), or 2. The particular recovery you're using is incompatible with the update.

I think it more likely that the custom recovery is the issue, so maybe try changing that?

EDIT EDIT: There's always a 3rd possibility - that you're device is not a grouper (wifi) but a tilapia (3g)?, as looking into the update script it specifies grouper, as does the name of the bootloader img file.

Also if the device wakes up because of an alarm, it's the same behavior, device irresponsible and Alarm - Sound in a loop (but this will wake you up in any case ;) ).
