Default interrupt storm and irq madness

Hey all,

i am running FreeBSD 7 stable i386 on my Toshiba Portege 3110ct. When I plug in my pcmcia Atheros wireless card I get this message a few times:

interrupt storm detected on "irq11:"; throttling interrupt source

This message was really bad when I had APIC compiled in the kernel, I do not know why but since I have taken that out it has mostly gone away. A vmstat -i without the Atheros card shows cbb0 (my cardbus) and uhci0 both using irq11. When I plug in the Atheros card the vmstat -i only shows cbb0 and ath0 on irq11 and does not show the uhci0. Now the cardbus is hard coded in the bios for irq11 and even editing the pccard.conf the Atheros card grabs irq11 also. I am only using 5 or 6 irq's (I am not at my laptop right now), is there anyway to force the uhci0 to another irq. The wireless works fine, i just do not like the interrupt storm errors. Does anyone have any other suggestions to fix this. I have read about the kernel parm to up the interrupt requests, but that just seems like I am supressing the messages of the real problem. Any help would be appreciated.

Sean
