Subjectradeon 0000:1d:00.0: GPU lockup (current fence id 0x00000000010da43f last fence id 0x00000000010da52d on ring 0)
Hi guys,

X just froze here ontop of 4.17-rc7+ tip/master (kernel is from last
week) with the splat at the end.

Box is a x470 chipset with Ryzen 2700X.

GPU gets detected as

What practically happened is X froze and got restarted after the GPU
reset. It seems to be ok now, as I'm typing in it.

Thoughts?
