[Bug 47481] Random blank screen: radeon_cs_ib_chunk Failed to schedule IB on AMD PALM

--- Comment #3 from Anisse Astier anisse@astier.eu 2012-09-13 17:27:23 --- I'm not sure. Since it's random I need to do a lot of tests to reproduce it. I'll try to test with 3.2.

Sometimes, screen might turn on, but I get vertical black and white stripes. (I have a photo if you need one).

My current stack is: - kernel 3.5.3, but it also crashes/bugs with kernel 3.6.0-rc5 - mesa 8.0.4 - DDX 6.14.4 - xserver 1.7.7

Not sure it's relevant since the problem starts before X when modesetting should kick in (screen is blank).
