https://bugzilla.kernel.org/show_bug.cgi?id=216171 Bug ID: 216171 Summary: Hibernation not working because of xhci_hcd Product: Drivers Version: 2.5 Kernel Version: 5.18.6-arch1-1 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: USB Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx Reporter: prz.kopa@xxxxxxxxx Regression: No Created attachment 301268 --> https://bugzilla.kernel.org/attachment.cgi?id=301268&action=edit 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 -Mathias
