Q: My phone as rebooted on its own or is stuck on a reboot loop.

A: There are 3 reason why your phone may reboot on its own:

1. Your phone does not handle the Undervolt of the kernel

Flash the stock voltage add-on. (NO I will not make the kernel with stock voltage by default)​

2. Your phone cannot handle the Overclock of the kernel

Use another kernel, Sorry...​

3. There is a bug in the kernel and I should fix it:

Post the /proc/last_kmsg output as a ZIP in the thread. BUT, before posting make sure the last_kmsg contains the mention "Kernel panic", if not, don't bother posting this because your problem is related to point 1 or 2...​

A kernel Panic looks like this:

Code:

[ 4079.850240] Kernel panic - not syncing: Fatal exception
[ 4079.850307] Backtrace: 
[ 4079.850504] [] (dump_backtrace+0x0/0x10c) from [] (dump_stack+0x18/0x1c)

Q: Why did you remove feature X?

A: Because I think it sucks
* This is my personal opinion and I am allowed to have it

Q: Can you add feature X?

A: Depends. Before asking that question, check the changelog.

If it was removed, NO.
* If you have a really good reason why you think a feature should come back from the dead, you can defend your case by PM.

If it's a new feature that I may not know about, just let me know of the feature and I'll consider it.

If its a new shinny CPU governor or IO scheduler, NO the ones that will remain do the job perfectly...

Q: What does feature X do?

A: Please try Google or Wikipedia before asking this. The answer is at the tip of your finger tips

There is definitely still work to be done and room for improvement but it does work.
