Same problem in Fedora 12: irq occupied by wlan0 causing problems...maybe
ndiswrapper is the source?

followed by more tracebacks related to irq event 17.  Invariably, the initial
problem is related to ndiswrapper.  Tried booting with irqpoll and irqfixup--no
change in behavior.

If you need more info, I'd be glad to provide it.
