4 is most probably used by Com1
6 , by floppy controller
7, parallel port
9 is shared with 2, so it is not a great idea to use it, though I
usually have to use, and I did not get much trouble
10 and 11 are great, usually 11 is for graphics card

Linux kernel does not control it. What you can do is at your bios,
and your hardware, plugging and unplugging the cards.

The soundcards irq may be changed by a bios setting, I dont know. If
there is something " reset pci configuration, escd or pnp conf. " or
something like that try to enable it , first. Then, go on trying to
change the irqs. You will need to make lots of resets. Usually, I turn
on a pc with no card added on it, then go on adding cards one by one,
so you see what is causing trouble.
Disable the usb, serial and parallel ports etc in your bios, if you
are not using them.
Sometimes, stupidly, changing the places of the cards solves some irq
troubles, but of course, you better try one by one, just to keep eye
on what is going on.
Having just 2 slots, is terrible enough... I have enough slots, but I
still am lacked on this !'^+ irq trouble so many times... 16 irqs are
not enough !
Wish you goodluck, hope these will help.
