Bug Description
Once updated kernel from 5.8.0-44 to 5.8.0.45, any use of Wacom stylus causes immediate system hang, frozen both GUI and OS. Removing the Wacom kernel module solves the problem (no more hangs, but the stylus is unusable then).
Rolling back to kernel 5.8.0-44 or any earlier solves the problem.
