Part of kern.log written during forcing a GPU reset
I've found that force resetting the GPU clears the corruption - using cat
/sys/kernel/debug/dri/0/radeon_gpu_reset
This does not take effect straight away however, I often have to kill Xorg
before it'll happen. There are some errors written to the kernel log - i have
attached those.
Here is lspci output for the card in case it's relevant:
