Comment # 5
on bug 95545
from Marek Olšák
The problem is with the CE preamble which is sometimes skipped when it shouldn't be. SDMA IB submission somehow affects it. The workarounds are: - disable SDMA (bad) - disable CE preamble (not so bad) - execute SDMA in a different amdgpu context (not tested, just an idea I'll try next)
