Hello,
I have a hard time making the 2.6-test11 to work correctly.
I constantly get messages about irq 18.
The kernel boots, linux works, but I get such messages every second :
Dec 7 18:28:24 pici kernel: irq 18: nobody cared!

I am using a P4 2.6 Ghz without HT activated
512 MB DDR PC3200 on an ASUS P4P800 Deluxe MB.
HardDrive is on SATA (native mode) : Maxtor 6Y120MO.
2.4.23 doesn't have this problem but keeps using 30-50% CPU even if I do nothing.
Attached is attached grep "=[y|m]" .config

Just to verify things, try booting with the 'noirqdebug' kernel parameter.
Then make sure everything works ok.

Sounds like the known problem with an interrupt storm with the ICH5
See "Issue #2" at
http://www.ussg.iu.edu/hypermail/linux/kernel/0312.0/0597.html

Try vmstat, I expect you'll see ~100k IRQ/s
You could try using the ata_piix driver (located amongst the SCSI drivers).
If that still doesn't help, you could try adding the patch attached to
drivers/scsi/libata-core.c
this should make the ata_piix driver catch the spurious interrupts
