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.
