wreninit() calls scsidrive() which issues test unit ready to
each id on the SCSI bus.

>D6.0.0.0: ready
>D6.0.1.0: ready      <--- the last message

Next wreninit() reads the capacity from each drive and prints
it out.  Since you didn't get that message, I suspect the
1542 has the DMA speed set too fast.

Run the host adapter diagnostics to find if this is the
problem.  Let it run through at least 2 full loops.  If the
machine freezes or crashes, slow down the DMA transfers in
the config section.
