Hi,

I've just recently hit this issue on ArchLinux kernel 5.14.7-arch1-1,
linux-firmware 20210919.d526e04-1 with a Thinkpad T495 AMD Ryzen 7 3700U along
a Vega Radeon RX 10 while using hashcat to brute-force hashes, hashcat was
using OpenCL in order to use the GPU and then the computer just froze, and a
GPU reset happened see the following logs.

Logs from dmesg:

--- Comment #1 from Lahfa Samy (samy@lahfa.xyz) ---
The computer did unfreeze then after the reset of the GPU but it seems hashcat
cannot use the GPU anymore for some reason, I'm not too sure why, but I think I
need to reboot my machine.
