Hmmm... Interesting point on the curve. Of the two systems that
I'm testing on, the system that is subject to the 127/128 flu DOES have
an IDE drive (and CD-Rom), in addition to SCSI drives, while the system
which is not subject to the flu does NOT have an IDE drive (but does still
have an IDE CD-Rom), only SCSI drives... Possible. Consistant with my
setup and observations.

Additional point, since a couple of people have mentioned swapping...
The system subject to the flu has the swap partition on IDE. The other
system, obviously has swap on SCSI... Could this be related?

Haven't seen this though...
