I was using this SCSI card to talk to a loaned tape library. I was
having flakiness where very other reboot the kernel would not report the
tape drives and instead would report two uk SCSI devices. I changed a
terminator and suddenly it would always notice the tape drives, but the
"chio status" command would hang and never return.
Forcing a reboot caused a kernel panic as the kernel loaded. Even the
library was clearly in an inconsistent state (it mentioned it couldn't
talk to the drive the changer hardware was hung off of). However, I
wouldn't think the kernel should panic, even if things aren't quite right.
I've since moved the card into an amd64 box and everything works
swimmingly. The card is a PCI-X card which I had in the Ultra 45
because it was the only hardware I still had with PCI-X slots. The new
box just has regular PCI, but the cards are still compatible. But I
wanted to include that detail.
Below I include the kernel boot/dmesg leading up to the crash along with
the trace and ps. ddb mentions doing a "mach ddbcpu <#>", but when I
tried that it told me I had issued an invalid command.
