I fear you will find Adaptec support WORSE, not better in kernel
2.4. Seems some folks purporting to be Adaptec officials and
with credentials suggesting the same made an appointment to work
with one of the kernel authors... And then they no-showed. The
kernel traffic articles on linuxcare recounted the circumstance
and described it as yet another example of Adaptec going out of
its way to be uncoooperative.
THe 2940U2W controller has how many different firmware versions?
Adaptec knows but it isn't telling, as usual. This particular
brand is a nightmare to keep up with. I recall something like 17
or 19 versions of the 2940. I no longer politely express my
concern to Adaptec, I just avoid their products.
