User reports hard system freezes which happen some time after resume from
sleep. Appears to be related to btusb and device 04ca:3802 Lite-On Technology
Corp. Wireless_Device, a Mediatek USB Bluetooth module which is internally
connected in this case.
Freezes began after upgrade to kernel 6.11.0, latest log is with 6.11.2-1
Multiple logs show this sequence of events
1. resume from sleep
2. usb 1-4 errors
3. `kernel: Oops: general protection fault` (hci_unregister_dev,
btusb_disconnect)
4. `kernel: BUG: workqueue lockup` several times that match the oops
5. total freeze, presumably kernel panic
