Bruce,

So , problem is inside 11 MB   patc= h-2.6.36-git13.bz2 . Might be it gives 37-rc1,
i am not sure. If you wan= t , i can try to send it to you.

Boris.
P.S. Bisecting 36 - 37-rc= 1 is too much anyway.

I picked= 2.6.36 - 2.6.37-rc1 as the bisect range and my first 2 bisects all panic a= t boot so I'm obviously doing something wrong.

I know that. I was asking what version = worked for you in the past. As in, did you do
