Booting with irqpoll works

ls /proc/irq/21/ (with irqpoll)
ehci_hcd:usb1/  smp_affinity  uhci_hcd:usb2/  uhci_hcd:usb3/  uhci_hcd:usb4/

irq 21: nobody cared (try booting with the "irqpoll" option)

Was any earlier kernel version OK?  2.6.23?

I've started seeing this too, sometime at or after 2.6.24-rc1.  2.6.23
was OK.  In fact 2.6.23-git14 or so was fine...  There have been
enough other regressions though that I haven't had time to bisect this
one.

Yes the 2.6.23 kernel works fine. This seems to happen when I boot the 
2.6.24-rc1 kernel with an iPod attached (hope this helps), but the 2.6.23 
kernel doesn't experience this problem.

..

Something in 2.6.24-rc* seems to be a lot more fussy about this kind
of situation than in 2.6.23.   I have a driver (sata_qstor) that manages
a piece of hardware that unfortunately generates spurious interrupts
regularly.

With 2.6.23, it was only rarely bad enough to cause the "Disabling IRQ #nn"
event to occur.  But in 2.6.24-rc*, it happens almost immediately now
(so, yes, I've gone and put a workaround into the driver for it).

Something's different.
