Dmesg log with failed hibernation attempt

Starting from 5.18.4 my notebook (Dell Latitude 3340) won't hibernate - hibernation fails with dmesg errors related to xhci_hcd. I'm attaching dmesg log with failed hibernation attempt. Problem goes away after reverting commit 63acaa8e9c65dc34dc249440216f8e977f5d2748 (USB: hcd-pci: Fully suspend across freeze/thaw cycle). After reverting this commit on linux 5.18.6 my system can again successfully hibernate.

Looks like there is a pending wakeup:

[   30.475168] xhci_hcd 0000:00:14.0: PM: pci_pm_freeze(): hcd_pci_suspend+0x0/0x30 returns -16

Guessing suspend_common() in hcd-pci.c retruns -EBUSY because HCD_WAKEUP_PENDING(hcd) flag is set.

Does xhci dynamic debug show some port event before this?

mount -t debugfs none /sys/kernel/debug
echo 'module xhci_hcd =p' >/sys/kernel/debug/dynamic_debug/control echo 'module usbcore =p' >/sys/kernel/debug/dynamic_debug/control

Thanks

There are a few "Port change events", I attached dmesg log with dynamic debug enabled.
