I've seen some CD-ROM drives claim to support UDMA2 but not work
properly in UDMA mode. You could try setting the flags to disable DMA
on it, see atapiscsi(4). 'boot -c' to enter UKC [see boot_config(8)];
'change atapiscsi' and set the flags accordingly.
This may or may not help, but it's worth a try. Definitely try a
recent snapshot also.

I have tried disabling UDMA, and UDMA and DMA, with no change. I have
also tried the latest snapshot from ftp.
Any more ideas?
I have found a PR4570 which seems to be a similar problem.
Interestingly, this was with an nForce4 chipset, whereas my chipset is
Intel.
Thanks,
