Interesting. This worked (and only disabling ultra-DMA did not),
although I still got some console spew:

cd0(pciide0:1:0): illegal request, data = 00 00 00 00 64 00 00 00 00 00
cd0: dos partition I/O error
wdc_atapi_intr: warning: reading only 1 of 2 bytes
wdc_atapi_intr: warning: reading only 1 of 2 bytes

Perhaps the first two messages are irrelevant, and the DMA version of
whatever is triggering the latter two was the problem?
