Subject: AMDGPU crash on 5.4.7 on AMD Athlon 3000G APU

Dear all,

There seems to be a regression between kernel 5.4.6 and 5.4.7. When I 
change from kernel 5.4.6 to kernel 5.4.7 I can no longer load the AMDGPU 
driver. The kernel immediately crashes with the following stack trace 
and errors. The system has to be hard reset to boot again.

The previous kernel 5.4.6 worked with no crashes. There was still the 
same stack trace, but no "Wait loop timed out" or "iommu ivhd0: AMD-Vi" 
error. Same kernel .config was used for both kernels.

The system is small headless machine with the new low-power AMD Athlon 
3000G APU with integrated VEGA 3 graphics (4)
Motherboard is a Gigabyte B450M. Two intel PCIe NICs are present.
