I have used dual AMD rx6800 on Win11 and it worked fine. Just recently tried same config on Ubuntu 22.04.1 and stuck.
Followed AMD instructions to install AMD drivers and ROCM.
All went fine, then downloaded the latest hashcat and built, no errors. But when i tried to benchmark it failed.

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.
