I'll put your patch on the VM in question. Btw. it has been up for 6 days now without a crash.

Before I do that I would like to see that it really addresses PR 201912.

Do you have any idea how I could provoke that one ?

Ideally I would like to do the stuff that forces the panic, then apply
the patch and see that the system stays stable despite me doing the
silly moves again.

Greetings
Christian
