Hi Ben,
I don't see any hardware errors in dmesg/messages.  What brand of SATA card
would you recommend?  Most of the cheapies are some variant of Silicon Image
3114/3124/3512.  It's also darn-near impossible to find something at retail
that's not cheesy "RAID".  :)

I'm not sure how I'd check that, but for perspective, this is a 5U
storage-oriented chassis with 24 disk bays, only 6 of which are currently in
use, plus the OS drives in 2 internal bays.  We used to run this system with
Linux using 16 SATA drives and 2 3ware controllers, so I'm pretty sure the power
supplies are up to the task with the current load.

No, I was referring to the default name of the ZFS root pool, as in:

rpool/ROOT/snv_99

I thought that as well, and it reports nothing.  :)

I'll try the cable swap, and if that doesn't nail it, an add-in card.  However,
The device names will change when I move off the onboard ports, and in the past
I've not been able to recover from that.  I'm guessing that GRUB needs to be
updated somehow-- is it a matter of booting failsafe, importing the pool, and
re-installing the stage1/stage2 files?
