timeouts with linux-2.2.13

[Elgin Lee]

I don't know if this is true for you, but my problem went away when I
used SCSI SELECT to reduce the speed for my IBM DGHS09U from 40Mbps to
20Mbps.  I suspect cabling issues at this point, as my SCSI cable
chain is probably at about the length limit for 40Mbps operation.

As to why it worked before my upgrade, perhaps the new driver is
faster than the old one! :-)
