> Can you bisect?

I have never bisected a kernel, but I can try. Just have a few doubts.

1 * Can I do with the Ubuntu kernel as per Ubuntu instructions[0] as:
$ git bisect start Ubuntu-2.6.35-1.1 Ubuntu-2.6.34-5.14

Which seems a saner incremental interval of Jun5 -> Jun 4.

Whereas Mainline Kernel 2.6.35-020635rc1-generic #020635rc1[1] which is dated
Jun 1 had the problem , but Kernel 2.6.34-02063407-generic #201009140905[2]
dated Sep 14(!!!) did not have the problem.

2 * Are there any pointers to narrow down the kernel commit from the backtraces
I have posted?
Or is just looking for "drivers/gpu/drm/radeon/" the closest?

3 * Is there any specific command I need to run if I hit the bug? 
Or is gdb of X sufficient? 
Do I need to set any variables to get better logs of the freeze?
(This is a very random bug which can sometimes take days, would be nice to know
just to be prepared. And I dont know much about kernel, hence the Qs.. :D )
