Bug Description
I've been experiencing all sorts of strange behaviour since upgrading to linux mint 21.
* adapter failing to power on after suspend/resume
* random errors littering dmesg
* now it went ballistic and caused my UI to freeze, not from anything I could identify that I did.

I have Intel Corporation Wireless 7260 (rev 73) with 8087:07dc Intel Corp. Bluetooth module.
From time to time, pausing and playing audio over A2DP causes Bluetooth stack to stall with the following in kernel log:
Bluetooth: hci0: command 0x041f tx timeout
Bluetooth: hci0: command 0x0406 tx timeout
Bluetooth: hci0: command 0x0c03 tx timeout
Bluetooth: hci0: HCI reset during shutdown failed

Bluetooth: hci0: urb 00000000215e997b failed to resubmit (113)
Note that "HCI reset during shutdown failed" happened when I tried to disable Bluetooth and enable it again.
Removing btusb and btintel modules and inserting them again helps.
