No luck here I'm afraid - I'm having a hard time reproducing it during normal desktop usage (with or without the patch), but it did lockup while running Unigine Valley.

Assuming you can still access the box over the network after the lockup then please provide the output of the following as root:

cat /sys/kernel/debug/dri/0/amdgpu_fence_info hexdump -s 0x14fc -n 4 /sys/kernel/debug/dri/0/amdgpu_regs
