[SWLUG] "disabling irq 9" kills net connection

[bascule]

using ndiswrapper to load the driver for my ralink rt2500 chipset wireless 
pcmcia card i've started getting the following message sometime after 
bringing up the wlan0 interface:
irq 9: nobody cared!

Disabling IRQ #9

from this point on, no amount of ifdown/up[ wlan0 or rmmod/modprobe 
ndiswrapper or service pcmcia restart will bring back the wireless 
connection, i have to reboot to get it working again, i did some googling and 
came across a suggestion to use 'nodebugirq' as a boot option which i'm 
trying now, i've been compiling kernels and only after the last compile did i 
notice this message, is there some option that i might have en/disabled that 
might cause this?
