 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
 me right now, and yes, I don't have the time, either. I say close it,
 and if I feel the inclination in the future, I'll open another, more
 relevant PR.
 
 Thanks,
