It looks like the driver is not ok with your controller/disk. You
didn't explain how many disks you have, or show the dmesg from the
controller being probed.
I would try using dd to read from rwd0d, at various places, and see if
you can discern a pattern.
Where is your root fs in netbsd? something else?
You might also try reading ixpide(4) and recompiling a kernel to have
the no-dma flag.
