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 ha=
ve
attached those.

Here is lspci output for the card in case it's relevant:
