Description:
I have a Problem with a corrupt Header on my AMD RX VEGA 64 Card after shutdown the VM.
The GPU is with vfio in Qemu VM.
arch linux kernel 5.5.10 and linux-lts 5.4. make this BUG on my KVM server.
I downgrade the kernel to 5.3.5 an the corrupt Header is fixed.
I have mesa beta 20.0.1 and archlinux 19.3.5 tested. and the BUG is not fixed.
see the log lspci -v > lspciv1.log for the 5.3.5 kernel loading in VM after shutdown.
see the log lspci -v > lspci_header_corupt.log for the 5.4.26 or 5.5.10 kernel loading in VM after shutdown.
see the dmesg >vfio_5.3.5.log for the 5.3.5 kernel loading in VM after shutdown.
see the log dmesg > vfio_5.4.26.log for the 5.4.26 or 5.5.10 kernel loading in VM after shutdown.

the gpu corrupt header has a gpu then not colling any more and fan rpm of 0.
hte gpu 30min - 40min fan of 100% and pc must remove for engine and waiting 15min gpu coling down.



Additional info:
* linux linux-lts mesa 19.5.3
* config and/or log files etc.

I have blacklist amdgpu and radeon and the header is after poweroff or reboot good in Sever.
Problem gpu cant't use with blacklisting amdgpu driver.
