Whohoo! It applies/builds cleanly to 4.1.10-rc1 and is running as
we speak. Let's hope that this fixes the lockups.

It definitely should help !

David, since patch is not yet seen on
http://patchwork.ozlabs.org/bundle/davem/stable/?state=*
could you please add it to your queue ?

Seems to fix it for me as well. 3 systems have been running varying
types of production-like loads with it for 14+ hours without hanging.

Just got up, and yes - my systems survived the night as well, no issues.

Greg, any chance you can drop this into the pending 4.1.10? Otherwise people
will get another broken release.

Fixes the problem here, too.
