I'm getting this kernel panic too, and unRAID freezes and usually has a black empty screen when I plug my monitor in.
Managed to snap a pic of the error on my phone on 10th March, pic attached. After this I set up a server syslog.
Today, I had another crash/freeze, but no error message, just a blank screen. Attached are my diags and syslog (I hard reset my system at Mar 28 11:24:54)
Overall it's frozen/crashed like this about 4 or 5 times in the past couple of months or so.
