I'm seeing a similar problem in 7.1 when sending "sysinst_com0.fs" to a
7248-132 with BOOTP/TFTP. The transfer looks to go through ok, but get
this output on the serial port:

>> NetBSD/prep BOOT, Revision 1.9

INTRF
phase mismatch without command
selection timeout without command
unhandled scsi interrupt, sist=0xffff sstat1=0xff DSA=0xffffffff
DSP=0x7f7e9fff
XXXXX: fatal error, need reset the bus...

...loops from INTRF...
