I tried booting up 2.0.35 to see if my tape drive would work any better with the older driver, but it wouldn't boot at all because the 2940UW is sharing IRQ 10 with a Promise Ultra 33 IDE controller. I'm very nervous about this IRQ sharing thing, because I think the IDE controller may have some IRQ sharing bugs. My peace of mind is not helped by the fact that I had filesystem corruption when I booted back into 2.1.131. It's not uncommon to get a few "delete inode had 0 dtime" errors, but this time there were thousands, plus a few random unattached inodes hanging around. Not good. I've also noticed some momentary mouse-tracking freezes during heavy disk activity, which I never saw before (serial mouse). Is there some way to force the aic7xxx driver to use another IRQ? The current setup is: 0: 298223 XT-PIC timer 1: 5682 XT-PIC keyboard 2: 0 XT-PIC cascade 3: 29441 XT-PIC serial 4: 0 XT-PIC serial 5: 0 XT-PIC Sound Blaster 16 8: 2 XT-PIC rtc 9: 3 XT-PIC eth0 10: 62513 XT-PIC ide2, aic7xxx 12: 103520 XT-PIC serial 13: 1 XT-PIC fpu NMI: 0 IRQ 15 is assigned to the other add-on serial port (unused now but will connect to a GPS), and IRQ 7 is assigned to the parallel port, which has a printer on it. Is there some reason why either the 2940UW or the UltraDMA card can't use IRQ 11 or 14? -Randy To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
