I experienced a series of AHA-2940 lockups under heavy load both uni and multprocessor, running multiprocessor the lockups happened quite a bit faster than uniprocessor. It looks like you don't have a 21140AC but the media select might be better in the newer driver. I do recommend upgrading the aic driver, it really improved the stability. Check the commits on the aic driver. dave adkins
