Bug description:
[SRU Justification]
[Impact]
More and more USB device suspend failure are caused by the un-expected
HCD_FLAG_WAKEUP_PENDING on the USB host controller. It mostly happens on the
USB devices connected to the high-speed root hub. It randomly happens when put
the system into suspend
[Fix]
Fixed by the upstream fix
https://lore.kernel.org/linux-usb/[email protected]/.
Set wakeup to false if suspend type is either PM_EVENT_FREEZE or
PM_EVENT_QUIESCE
[Test Case]
1. Power on machine and connect a USB device to the high-speed root hub.
(Find your device in lsusb in the secondary root hub)
2. run checkbox-cli run
com.canonical.certification::suspend-cycles-stress-test
3. observe the suspend/resume fail with the kernel message
[Where problems could occur]
Add more restriction on how the wakeup should be performed. Should be low risk
