I ran into this error message and problem straight after installing
Dapper. "irqpoll" didn't help me either (the machine hung hard instead).
I notice that your /proc/interrupts has a suspiciously round number. I
found that when an interrupt packed in (for me it was usually USB or
sound, with concomitant symptoms), the interrupt count displayed in
/proc/interrupts was *always* a multiple of 100000 (and sometimes
implausibly large). For instance, see IRQs 11 and 185:
$ cat /proc/interrupts
CPU0
0: 2455783 IO-APIC-edge timer
1: 3979 IO-APIC-edge i8042
7: 0 IO-APIC-edge parport0
8: 3 IO-APIC-edge rtc
9: 1 IO-APIC-level acpi
11: 200000 IO-APIC-level uhci_hcd:usb1, uhci_hcd:usb2
12: 78674 IO-APIC-edge i8042

169: 1080436 IO-APIC-level nvidia
177: 146 IO-APIC-level eth0
185: 600000 IO-APIC-level Ensoniq AudioPCI
NMI: 0
LOC: 2455610

For me, the workaround is to add "noapic nolapic" to my kernel command
line. (May be a sledgehammer to crack a nut, but it works. I got it from
Wikipedia, of all places.)
The motherboard is an MSI K7T Turbo2. (I can post lspci type spew if
anyone's interested.)
Hope this info helps somebody. This was very frustrating until I found
the workaround.
