[drm:r600] UVD not responding OR failed testing IB on GFX ring
Submitted by Timothée Ravier
Assigned to Default DRI bug account
When I boot 3.10 or 3.11 kernels, I get either one of those errors, apparently at random :
- UVD not responding, trying to reset the VCPU
-> Full log attached: *freeze-boot-then-yellow.log
The display turns yellow when the X server starts. I can still use VT and there is no corruption there. I made sure that I got the latest firmware and I also checked my initrd (following instructions in 65270);
* GPU lockup CP stall for more than 10000msec
GPU lockup (waiting for 0x000000000000020e last fence id 0x00000000000001ec)
r600_ib_test] *ERROR* radeon: fence wait failed (-35)
radeon_ib_ring_tests] *ERROR* radeon: failed testing IB on GFX ring (-35)
-> Full log attached: *freeze-cursor.log
I can log into my graphical session, but quickly after that, everything freeze and I can only move the cursor which displays as a "corrupted" square.
Again VT are fine.
I filed only one bug report as I get both issue using the same software and boot command line.
At the beginning I had bug 67994, which turned into this one. I tried downgrading the kernel without much success for now.
Booting with nomodeset works perfectly (with no accel/KMS obviously) and booting under Windows 7 too.
