Kernel panic/dump: ffs_valloc (dup alloc) + request for a leaf account

[Steven Looman]

As Erik P. Skaalerud pointed out, the board (and the raid controller) is 
buggy.

I'm using the raid controller because I suspected there were problems with 
the normal controller.

Guess I'll grab another board and make that my test/playing machine.
