amdgpu: *ERROR* Waiting for fences timed out!

[Ilkka Prusi]

Hi,

I got this error in kernel log from desktop freeze, it still responded 
to SysRq and system could be killed but desktop was unusable. I assume 
this might explain some problems I have seen on this computer before.

I assume that preceding segfault has no meaning here but included it anyway.

System has:

- Linux version 5.7.6 (gcc version 9.3.0 (Debian 9.3.0-14), GNU ld (GNU 
Binutils for Debian) 2.34) #2 SMP PREEMPT

- AMD Ryzen 7 2700 (Family 17h (Models 00h-0fh))

- [AMD/ATI] Vega 10 XL/XT [Radeon RX Vega 56/64] (rev c3)

- DMI: TUF B450-PLUS GAMING, BIOS 2008 12/06/2019
