With *some* Adaptec 2940 cards (I don't think there is a comprehensive list of those who work and those who didn't), the new 5.0 Adaptec driver (which appeared with kernel 2.0.34 and was lihlty updated in 2.0.35), fails: CD-ROMs not detected at all, various errors at the intialization or after, in heavy use.
On the same machines, 2.0.33 runs perfectly fine. For the people with theses cards, 2.0.34 was not a maintenance version :-(
If you need 2.0.35 features and if, after testing, you see that you are the lucky owner of one of the offending cards, just copy drivers/scsi/aic7xxx* from the 2.0.33 tree in 2.0.35 and recompile. It works for me.
If you have several important machines with Adaptec cards, I suggest you subscribe to the aic7xxx mailing list @freebsd.org (Linux and FreeBSD coexist on the list). This problem has been discussed here.
