Public bug reported:
Hello.
Running Ubuntu 18.04 (4.15.0-22-generic), after plugging my TP-LINK TL-
WN722N into the USB port, the CPU usage goes to 100%, and there are
multiple reports of "stack traces" in dmesg.
The attached snippet repeats multiple consecutive times in the dmesg
output (albeit with a different trace id).
