Bruce,

I just tried 2.6.36 + patch-2.6.36-git13 via patch-2.6.36-git13.bz2 ( i picked it up from MY's first kernel-2.6.37.fc15.rc0.git13.src.rpm ). Kernel 2.6.36-git13 already has a BUG .
So , problem is inside 11 MB   patch-2.6.36-git13.bz2 . Might be it gives 37-rc1,
i am not sure. If you want , i can try to send it to you.

Boris.
P.S. Bisecting 36 - 37-rc1 is too much anyway.

The git bisecting is slow going. I've never tried that before and I'm a git rookie.
I picked 2.6.36 - 2.6.37-rc1 as the bisect range and my first 2 bisects all panic at boot so I'm obviously doing something wrong.
I'll RTFM a bit more and keep at it.

I know that. I was asking what version worked for you in the past. As in, did you do
the same tests with older kernels (2.6.36 for example?)
