I would prefer to see the underlying cause for this problem figured
out. Why is the USB3 port stuck in polling mode? Is it a hardware
issue or a software bug?
More detailed debugging logs might help.
Sure, please see the requested logs attached. Thanks for taking a look.
Thanks
journalctl.log shows port 2 is in Polling state (2e0), and stays there,
but no reason why, or how it ended up there.

Same with xhci_hcd_trace.log, port is in polling state since the beginning of the log.
Can you check the port states before first system suspend attempt:
cat /sys/kernel/debug/usb/xhci/0000\:00\:14.0/ports/port*/portsc
-Mathias
The output of the port states you sent before the first system suspend attempt,
immediately after reboot shows no issues yry.
No port is stuck in polling.
Maybe initiating suspend causes the port to end up stuck in usb3
polling state.

Can I ask you to take yet another set of logs, same as before, xhci traces, and
usbcore and xhci dynamic debug, but preferably everything from boot up to and including
a failed system suspend event.
Thanks
