I also see a bit more from the panicking dmesg boot above this:
amdgpu0 at pci9 dev 0 function 0 "ATI Radeon Rx Vega" rev 0xc1
drm0 at amdgpu0
amdgpu_acpi_enumerate_xcc: stub
amdgpu0: msi
Which comes from:
static int amdgpu_acpi_enumerate_xcc(void)
{
STUB();
return -ENOSYS;
#ifdef notyet
<...>
#endif
}
Not familiar enough to understand if this is part of the problem, but
thought it was worth adding to the bug report.
