I get this same "error" with hpt370 controller (Abit KT7A-RAID), but only if I have more than one disk attached. I recently added a second disk to the second controller and got this since. Everything seems to work ok so it might be only something the ide-driver doesn't understand when one chip has two ide-busses sharing the same interrupt. I commented the printk out from ide.c and haven't had any problems with it.

I'm having the same problems on dual PIII (VIA chipset) with addon Promise IDE card:
Apr 24 19:34:51 atlas kernel: ide: unexpected interrupt 1 11
Lots of those...
Looks like it favors additional IDE interfaces. As system appears to behave sanely, modulo flooded logs, I decided to comment the printk for the time being.
Ingo, does it have anything to do with your interrupt balancing code? If you need additional testing, let me know.

That's fine and it will be gone in 2.5.11. The message is

No no no. It's really harmless. It is affecting add on interfaces becouse they are likely to share interrupts with other devices.
