            Bug ID: 218546
           Summary: xhci_hcd prevents hibernate/S4 suspend from working on
                    several systems
           Product: Drivers
           Version: 2.5
    Kernel Version: 6.8.0-rc5
          Hardware: All

          Severity: normal
          Priority: P3
         Component: USB

When running disk suspend on certain platforms the xhci_hcd USB3,0 hub
controller device prevents hibernate by aborting suspend. The test is initiated
with this command:

$> sudo sleepgraph -m disk-platform -rtcwake 60 -dev
This essentially performs these two commands to issue the suspend:
$> echo platform > /sys/power/disk
$> echo disk > /sys/pwoer/state

The dmesg log shows the error where suspends is aborted:

xhci_hcd 0000:00:14.0: PM: pci_pm_freeze(): hcd_pci_suspend+0x0/0x20 returns
-16
xhci_hcd 0000:00:14.0: PM: dpm_run_callback(): pci_pm_freeze+0x0/0xd0 returns
-16
xhci_hcd 0000:00:14.0: PM: failed to freeze async: error -16
usb usb1: root hub lost power or was reset
usb usb2: root hub lost power or was reset
PM: hibernation: Basic memory bitmaps freed
PM: hibernation: hibernation exit

I'm attaching 3 sleepgraph timelines from three different production machines
where this happened, so it's not endemic to just one manufacturer. The dmesg
logs are in the timeline itself, just click the dmesg button in the upper left
corner. The log button in the upper left corner shows all kinds of system
details.
