from Linnea S
I'm also hitting this bug with MSI R9 390 and kernel 4.19.2-300.fc29.x86_64. It works with 4.18.17-300.fc29.x86_64. Boot options: radeon.cik_support=0 amdgpu.cik_support=1 amdgpu.dc=0 amdgpu.dpm=1 Please let me know if there's something I can try to help troubleshoot this issue. Backtrace: ------------[ cut here ]------------ Memory manager not clean during takedown.
