Hi Bert,

I am glad to hear that mentioned patch fixed your issue.
Small clarification - amdgpu is not designed to support
PREEMPT_RT flag, but it was still worth to fix as obvious regression.
Sorry for missing tags. Unfortunately change is already merged.
I will keep that in mind to add these tags for future changes.

Kind Regards,
