Description Ákos Szőts 2019-09-14 07:23:47 UTC 
When I suspend my computer to disk and reboot it into Windows, xhci_hcd reproducibly prints into dmesg the following message after Linux is restarted:

xhci_hcd 0000:2f:00.3: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0000 address=0xfff67040 flags=0x0020]

All USB bugs should be sent to the linux-usb@vger.kernel.org mailing
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.
