[Impact]
Devices affected:
* [1022:148c] USB controller [0c03]: Advanced Micro Devices, Inc. [AMD]
Starship
USB 3.0 Host Controller
* [1022:149c] USB controller [0c03]: Advanced Micro Devices, Inc. [AMD]

Starship/Matisse HD Audio Controller
Despite advertising FLReset device capabilities, performing a function level
reset of either of these devices causes the system to lock up. This is of
particular issue where these devices appear in their own IOMMU groups and are
well suited to VFIO passthrough.
Issue was introduced in AMD's "AGESA Combo-AM4 1.0.0.4 Patch B" microcode
update, and affects dozens of motherboard models across various vendors.

[Fix]
Two commits currently landed in linux-pci pci/virutualization:
* 0d14f06cd665 PCI: Avoid FLR for AMD Matisse HD Audio & USB 3.0
* 5727043c73fd PCI: Avoid FLR for AMD Starship USB 3.0
[Test Case]
Peform the test on an impacted system:
* B350, B450, X370, X470, X570 motherboards (practically anything with an AM4
socket);
* Ryzen 3000-series CPU (2000-series possibly also affected);
* BIOS/UEFI firmware that includes "AGESA Combo-AM4 1.0.0.4 Patch B" (check
vendor release notes)
In the above case where '0000:10:00.3' is the USB controller '1022:149c',
issue
a reset command:
$ echo 1 | sudo tee /sys/bus/pci/devices/0000\:10\:00.3/reset
Impacted systems will not return successfully and become unstable, requiring a
reboot. `/var/logs/syslog` will show something resembling the following:
xhci_hcd 0000:10:00.3: not ready 1023ms after FLR; waiting
xhci_hcd 0000:10:00.3: not ready 2047ms after FLR; waiting
