That's exactly what it says, in fact it usually prints this to the screen.

I reserved IRQ 11 and 12 for ISA devices in the BIOS, so I expect them to
be free. I can't get the wavefront driver to work on IRQ 9, 11, or 12. The
cs4232/ad1848 seem to be happy on IRQ 11 now. Both isapnp and conf.modules
are set up to for IRQ 11 and 12.
Everything used to work on IRQ 5 (cs4232/ad1848) and 9 (wavefront) but I
upgraded to a Pentium II BX motherboard and it went haywire. I'm now using
kernel pre-2.1.122-3. I noticed there were some wavefront changes in this
patch, but they didn't fix the problem.

The PS/2 mouse port and USB are disabled in BIOS, video card is on IRQ 10,
SCSI is IRQ 9, and network card is IRQ 5. I don't see a problem with the
interrupt configuration.
