Same here.

That's actually what it should do, and once already did here -- on a
4.6-STABLE box - older kernel's showed a similar behaviour.  I remotely
had the impression the box hung, but maybe it had the same symptoms as
your box.  What version are you using?

Anyways, I wouldn't actually recommend User-Hardware such as the
ATA-RAID-Controllers for production systems anyways.
