You may want to listen in to the mailings on aic7xxx@freebsd.org. As it stands I'm in the middle of writing a patch to fix the abort/reset processing as well as it adds a bottom half handler to the interrupt service routine to avoid high latencies in the interrupt processing that can result in the QOUTFIFO over flowing. Dan Eischen has already released one fix for the QOUTFIFO overflow problem (sent to Linus just a few days ago), but it is a spin lock and somewhat less elegant from the standpoint that it doesn't actually solve the latency problem. The final code will probably have my bottom half handler as well as the safety of a spin lock backup both in there. I'm also doing what I can to make sure we aren't getting bogus information from anyplace, which would result in the Aiee: type messages you mention. I expect to have the first publically available abort/reset fixes available for testing by either late tonight or sometime tomorrow.
