I have three systems, two with zip and one with jaz. the jaz system has
an uptime of 140 days and has 4 ide/2 scsi HD/1 scsi CD/1 jaz (one adaptec
2940). Every drive is used nearly every day.

Without sounding too much of a 2.1 advocate, I recommend you try it. The

The above recommendation is an idle speculation that may or may not be
correct. For those of you that are going to jump hogwild on me about
using 2.1 and stability, I have several [busy] machines with >120day
uptimes on them.
And for the record, these 2.1 kernels have been -more- stable than 2.0
with nothing changing except the kernel. The emphasis is that 2.1 is
the `development v.s. release' series, not `unstable v.s. stable'.
