[SunRescue] fun SCSI errors

[Dan Debertin]

I have a known-to-be-pretty-good Seagate drive that Solaris 2.5 just
hates. Here are some of the boot messages:

WARNING: /iommu at f,e0000000/sbus at f,e0001000/dma at f,81000/esp at f,80000 (esp0):
        Connected command timeout for Target 5.0
WARNING: /iommu at f,e0000000/sbus at f,e0001000/dma at f,81000/esp at f,80000 (esp0):
        Target 5.0 reducing sync. transfer rate

That is followed by SCSI timeouts for almost every disk on the bus.
When I remove this disk from the bus, everything works fine. It's a
Seagate ST51080N; the enclosure is centronics-50, which I convert to
narrow SCSI2 to plug into my 600MP.

The drive works fine on a NetBSD/i386 box, but maybe Solaris is more
sensitive or something. Termination is not a problem, and I have carefully
audited the SCSI ID's.

So ... any ideas?
