[784650.854439] BUG: sleeping function called from invalid context at 
kernel/rwsem.c:20
[784650.862280] in_atomic(): 1, irqs_disabled(): 0, pid: 247, name: kworker/1:1H

[... further messages and tracing causing a panic skipped]

I can resolve line numbers if required, but I don't have any minute to look into it myself.


Cheers,
Bernd
