I'd like to chase down the issue, but the system is pretty old, the
disk is a:
amr0 at pci1 dev 10 function 1: AMI RAID <Series 466>
amr0: interrupting at ioapic1 pin 8 (irq 14)
amr0: firmware <3.01>, BIOS <1.36>, 16MB RAM
ld0 at amr0 unit 0: RAID 5, optimal
ld0: 42840 MB, 10880 cyl, 128 head, 63 sec, 512 bytes/sect x 87736320 sectors
which is pretty ancient, and the system is about 16000km away from

and if I feel the inclination in the future, I'll open another, more
