[Bug 29556] [rv620] GPU reset followed by black screen

https://bugs.freedesktop.org/show_bug.cgi?id=29556

--- Comment #15 from Marc marvin24@gmx.de 2010-08-17 14:05:34 PDT --- the bug is hard to trigger (10 min scrolling with firefox), so bisecting will take a lot of time. I booted with no_wb=1 just for testing and now it seems to work fine. So maybe the blit and the writeback change have some unhealthy relationship. Also somehow the git history got changed... I'm sure the writeback changes where there many days ago and before the blit change. Maybe it also helps, that original reporter (Stefano) has a rv620 chip which is (AFAIK) similar to the rs780/785 chips.
