Dear Maintainer,

My laptop _sometimes_ doesn't suspend, leaving it in a state where
graphics in gnome-shell (Wayland) are in an unusable state, even though
GDM and non-graphic terminals still work. With the laptop in this state,
shutting down or rebooting won't work either, which seems to be caused
by a stuck kworker.

I'm seeing kernel messages that appear to point at a USB hub, and the
hung kworker is in Workqueue: usb_hub_wq hub_event [usbcore]. As far as
I can tell, it seems related to bluetooth, as it mainly happens at work
where I use a Bluetooth mouse. 

Full output of the kernel for the hung kworker and for the failed
suspend can be found here:

I'm currently running a kernel from experimental because it happened
with the testing kernel and I hoped for it to be fixed there.

The system has a Ryzen 7 PRO 3700U CPU and Intel Wireless + Bluetooth.

Kind regards,
