My machine won't boot with anything plugged into the USB ports.
This is actually the /var/log/kern.log from booting with 2.6.21
yesterday, but I got exactly the same booting up 2.6.22 with the USB
headphones plugged in. This doesn't happen with the vanilla 2.6.18 from
etch.

ad infinitum ... (at least until I take the USB device out)
This also happens similarly when I have attempted to boot with a USB
wifi dongle in too.
I don't appear to be able to find any logs from this morning's failed
boot apart from the less-than-useful /var/log/dmesg
I'll try rebooting with irqpoll option as suggested:
"""
The "irqpoll" option is a kernel arguement so it needs to be appended to
the kernel line of grub. So it should look something like:
kernel /boot/vmlinux-2.6.22-8-generic root=UUID=stuffhere ro
resume=UUID=stuffhere irqpoll
"""
From reading it seems that acpi=off may also be worth trying as this
could be a conflict between uhci-hcd and an ACPI interrupt. I have also
read reports of noirqdebug being useful. However, irqpoll and some of
the other options are known to do things like disable CD drives and mess
up keyboards, so none of these suggested workarounds look much like fixes.
It appears to be a common problem with 2.6 series kernels on older
hardware like mine.

I'd be interested to hear from anyone else experiencing irq conflicts
and lock-ups like this. It would be even cooler to fix it once and for
all. Suggestions, of course, welcome. :)
cheers,
