I had the same thing happen with IRQ11. Here is what I wrote to
someone else in comp.os.linux.misc previously:

<begin quote>
I *also* had a situation where SuSE was saying "IRQ 11: Nobody cared!"
and disabled IRQ11. In my case, The Ethernet port, the USB ports,
possibly the Sound Card, and a MIDI port were all using IRQ 11. The
last one appeared to be the culprit; it was old fashioned, someone
told me, from an era before IRQs were shared. None of the other devices
seemed to have IRQs assigned in the motherboard Setup, they had been
choosing IRQ11 on the fly as near as I could tell. But the MIDI port
was specifically using IRQ11 and not sharing, apparently. I disabled
the MIDI port and my Ethernet port, USB ports, and Sound Card all started
working.

My advice: Look in the Setup for devices that specifically use IRQ 11,
disable the ones you don't use, and switch the ones that you can.

Perhaps the same logic might apply here?
