Ok, so I hooked this up, enabled the builtin mirror, and got the panic.  I
didn't let the disks sync first, so I'm going to allow that to complete
then try again. I have a sinking feeling that the controller doesn't keep
track of the status of the mirror pairs too well and will allow you to
read blocks off the unsynchronized side of the mirror, which will result
in bizarre panics.

Hopefully I can keep the system on long enough to sync the disks ... the
disks I'm using need forced-air cooling or they _will_ melt.

As regards your vinum problems, I suspect thats a bug, unless your IBM
array has the same problem and it coughed up a corrupt block on an array
read.  I don't have the necessary equipment to replicate that
configuration or I'd test that too :-)
