hey christopher.

i'm having a similar problem here. i just started using usb to read cf
cards. this is what irq 11 looks like in my /proc/interrupts:

 11:        838         25   IO-APIC-level  ide2, usb-uhci, eth0

it's especially odd because after unloading and loading the usb driver and
other playing around i ran into a situation. i tried to cat
/proc/interrupts earlier today and got a seg fault. i tried to reboot the
computer remotely and it never came up. when i got home the computer had
frozen in the middle of rebooting. i found the following in my messages
log:

it seems like everything is using irq 11 :)

i'm not really sure how to deal with this. i sure miss the good old days when
you could set a jumper and the hardware would do what it was told.
