sil24 cards?

I also used it but it was back 2-3 years ago now. I think it even worked
back in 2.6.18.

So it's a bit difficult for me to get too much data on this since it's a
production system and downtime does come at somewhat of a premium.
However, if whoever may be able to work on it and see what broke (because it
almost works, I see all the drives on my PMP and I can read data somewhat, I
just get a lot of somewhat scary errors now) lets me know, if he/she has no
way to test him/herself, I'll see what I can do to help out and get to
replicate this with older kernels on either that server, or maybe another
machine I would have to build for it (trying repeatedly on production data,
even with backups, not so good :) ).
Thanks for the answer,
Marc
