More on the continuing saga of trying to use *two* Adaptec 3940 twin channel
controllers in the same system. Having not had a chance to go on-site in
about two weeks, my attempts to get this up and running were very limited
in scope until tonight.
The motherboard, an ASUS um. Argh. >:-( P54TP4? One of Rod Grimes' jobs.
Should be reasonable.
This is looking like it may well be a configuration problem, but I don't
really have a clue. I did some minimal debugging and tracing but it's not
clear to me how it's all supposed to work together.
It appears that getintdescbytag is getting called with the same values for
ahc0/ahc2 and ahc1/ahc3. I couldn't really make a lot of sense quickly out
of what was causing that, however, and I believe it is only a symptom of
something else that hasn't happened for that second controller.
Anyways, kudos to Bill Paul(?) for his serial console work. It makes it
very easy to catch messages. I have added a few of my own for debugging,
and made a few others a little more specific. None of the meanings have
been changed however.
If anybody who is familiar with this code can give me a suggestion about
what to try next, I would be grateful.
(and yes I know it's wicked to print pointers with %d)
