according to Matthew D. Fullers dmesg, it seems he has an Adaptec 2940UW
revision A (rev 0). I have the same card and I have experience the same
kinds of problems. My relevant system information is...

My problems appeared when I used the two config options AHC_TAGENABLE
and AHC_SCBPAGING_ENABLE in building my kernel. When I removed these
two options, the problems disappeared. A week or two ago, there was a
discussion of this for the Adaptec 2940UW revision E cards the stable
email list. As Chris points out, these issues have come up in the
past as well. I have not had a chance to dig into this issue, and I
won't until August (I'm defending my dissertation at the end of July).
I thought I saw some email in the past about the early (rev 0 or rev
A) Adaptec 2940s cards having problems. But I have not been able to
locate them in the archives to confirm this.
