--- Comment #10 from Richard Thier <u9vata at gmail.com> ---
I am getting really close to bisecting the bigger identified problem.

bad: b672c3833b7
good: aff1ad0798

Now at this point:

Bisecting: 9 revisions left to test after this (roughly 3 steps)
[3efedf98e8272d1a32a3837b22161582d28c4487] i965: Always flush caches after
blitting to a GL buffer object.

Also now compiation is not even taking an hour like before where bisect was
jumping big time periods as code barely changes I guess ;-)
