            Bug ID: 220667
           Summary: xhci_hcd prevents S3 suspend to RAM from working on
                    Zen 5 system
           Product: Drivers
           Version: 2.5
          Hardware: AMD
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: USB
          Assignee: drivers_usb@kernel-bugs.kernel.org

boot excerpt, followed by suspend errors

As of upgrading my system to a slightly patched build of 6.18-rc1 (not patched
in ways which should affect this bug), S3 suspend fails due to an empty USB 2.0
hub in the system.

Log lines related to the USB hub's PCI device, in attached log excerpts.

Using sysfs to remove the following device path:

echo 1 | sudo tee /sys/devices/pci0000:00/0000:00:08.3/0000:1a:00.0/remove

Allows the machine to suspend normally, and the device stays removed upon
resume.
