You want to check your log for any "ahc" error messages to get a better
idea of what happened prior to the crash.

Is AHC_SCBPAGING_ENABLE enabled in your config?  There was a bug with
SCB paging in 2.1.5-RELEASE.

There have been some changes to the aic7xxx driver since 2.1.5R, so you
might want to upgrade to -stable (if you can afford the down time).
