Today I tested 4.12 release on my RP3440 (HP parisc). It worked fine, 
then on shutdown I got this strange message from kernel after shutdown:

reboot: Power down
System shut down completed.
Please power this system off now.
BUG: workqueue lockup - pool cpus=0 node=0 flags=0x0 nice=0 stuck for 40s!

and this continues with longer and longer times.

Is it something hppa specific or general?
