radeon 0000:02:00.0: disabling GPU acceleration

English Hardware

This is one of the reasons I reinstalled. I couldn’t figure out why my GPU acceleration had been turned off.
It was working yesterday and this morning. I got home from work and my computer was locked up and I restarted it. I watched a video earlier this evening and didn’t notice but it was basically a slide show.
Now I was playing a video with motion and it was obvious.

I see these lines in the dmesg

2.178594] [drm] radeon: irq initialized.
2.343326] [drm:r600_ring_test [radeon]] *ERROR* radeon: ring 0 test failed (scratch(0x8504)=0xCAFEDEAD)
2.343328] radeon 0000:02:00.0: disabling GPU acceleration

I did some googling and it seems I need radeon r600 microcode, but I see where is Loading CEDAR Nicrocode.

Do I need to post my dmesg and Xorg.log?

I tried posting my dmesg but it said the post was too long.

I rebooted and the problem seems to be fixed.
