This is where it probes devices on the SCSI bus.  It can handle
version 2 PowerTec cards (mine at least).

When I fitted my PowerTec a few weeks ago I initially had a similar
problem.  It would give the output you reproduced above, report the
first two SCSI devices, and then hang.  Interestingly, RISC OS also
had problems with the third device.  *Devices would crash at the same
point.

I double-checked the termination settings (the two devices at the ends
of the SCSI chain should be terminated, and nothing inbetween should;
this may involve fitting resistor packs to those devices and/or moving
jumpers on them; if one of them is the PowerTec card itself it
involves a *Configure command; if not you probably need to do the
opposite *Configure command).  Then I unplugged everything from the
SCSI bus and put it back together.  The second time I did that, it
magically started working.  Touch wood, it'll keep working.
