On the radoen module load, I got this error:
[ 9.874444] [drm:r600_ring_test] *ERROR* radeon: ring test failed (scratch(0x8504)=0xCAFEDEAD) [ 9.874447] radeon 0000:01:05.0: disabling GPU acceleration [ 9.875771] radeon 0000:01:05.0: ffff88043c78dc00 unpin not necessary
This is intermittent. I got theses error two weeks ago and it vanish after a reboot about 1 week ago. The video acceleration was working perfectly until yesterday reboot (adding an option in the kernel) and now the problem is back.
After the problem came back, I tried booting on the 3 others kernels I used this week (when it was working correctly) and the problem is still there with them.
I have attached the dmesg and my .config if this can help find the problem.
