I can't be certain, but I'm pretty sure that my root sector (and a bunch of others) were trashed due to some malfunction while the 2940UW was trying to share IRQ 10 with a Promise Ultra33. The Promise Web site mentions that there have been problems w/ IRQ sharing in this card, which are supposed to be fixed by BIOS version 1.25--I have 1.23. Fortunately, during my attempts to bring the system back to life, the Ultra33's IRQ moved up to 14, where it's out of the way, and things seem to be working normally. I have no idea if there were any bugs in the aic7xxx driver that played a part in this, but I thought I should mention it here just so we have a data point. Now that I'm once again able to boot 2.0.35, we'll see if the tape drive works any better.... -Randy To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
