Hi Amy,

it happens with AutoCtk (https://github.com/ksettaluri6/AutoCkt), so some
Python code. Everything runs fine with kernel 5.7.2, last week we went to
kernel 5.9.1 and this bug appeared. Today I've tried with it kernel 5.9.8, but
no luck.

The machine is unstable after this bug happens. The load goues up but we can't
kill the python processes, they're all in state D. Also, a clean reboot is not
possible, only a hard reset helps.
