Well like I say it's crashing after 5 minutes and I can't use the ROCm kernel anyway (or amdgpu-pro driver either because I'm using Debian now but apparently you don't need that).
When you say it's 0.5Mh/s below Windows do you mean with or without the dag fix?
even with DAG fix the hashrates I get is 0.4-0.5 lower on same card same clocks on win 10.
