zippo# dd if=/dev/zero of=/dev/rst0 bs=32k count=1
1+0 records in
1+0 records out
32768 bytes transferred in 1 secs (32768 bytes/sec)
zippo# dd if=/dev/rst0 of=/dev/null bs=16k
dd: /dev/rst0: Input/output error
0+0 records in
0+0 records out
0 bytes transferred in 12 secs (0 bytes/sec)
zippo# dmesg | grep st0
st0: 32768-byte record too big

NetBSD 1.2/i386, ahc.c <EXABYTE, EXB-8200, 425A>

but with NetBSD 1.2/i386, ahb.c <WangDAT, Model 3400DX, 1.0w>
it hangs the bus on the first command.
