Sounds like a driver problem -- maybe a missing or late interrupt.
I dont know enough to diagnose it further.

As of 1.3.x, NetbSD and FreeBSD use the same MBR partition-ID to mark
their MBR partitions ("slices"). Trying to install 1.3.2 onto the
same disk as FreeBSd is going to lose. NetBSD-current assigns a new ID.
