Yeah, looks like a BIOS problem. But the driver should handle that
without crashing the system, so there is a bug in the driver too.

Problem is:

AMD-Vi: DEV_ALIAS_RANGE devid: 0a:01.0 flags: 00 devid_to: 0a:00.0
AMD-Vi: DEV_RANGE_END devid: 0a:1f.7

This means that PCI devices from 0a:01.0 to 0a:1f.7 may use their own
device-id or 0a:00.0. But a device which id 0a:00.0 is not present in
the system. From the lspci output this looks like your USB3 controler
should alias to 09:00.0. I prepare a patch for you to fix the crash but
I can't guarantee that your USB3 controler will work afterwards. If you
see IO-Page-Faults please report them to me.
