Hannes,
Yes, I was mimicking a SAS drive with the secondary port
unconnected.

I'll have a look, perhaps it could be wired when
vpd_use_hostno=0 .

Umm, I would like to find out why that patch oopses
my machine when I load the scsi_debug module.
lk 2.6.19-rc2 has regressed in a few areas, for example
after an oops, inane messages from atkbd repeat ad
nauseum, making the oops hard to analyse. And my SMC2835W
(prism54 driver) no longer works.
