This thread:

concluded that the IDE controller was ultimately responsible, in that 
particular case. However this person had no luck with disabling acpi, 
even though the error messages were similar to yours.

Can you go into your BIOS and assign the USB controller to a different 
IRQ? Sometimes the 'reset BIOS to defaults' option can help.

The interesting question is why Debian's stock 2.6.18 was OK on this 
hardware, but our recent RT kernels are not.

Have a good weekend!
