Uh, oh.  Smells like an apic problem to me.

Gee, I don't get that.  I'm using a Fujitsu Lifebook C2200 on the stock
FC4 kernel:

Although we appear to have the same wireless chipset, I am using an
older Broadcom driver.  It works with the default 4K stack kernel.  I'd
try a couple of things:

1. Try booting with the "noapic" option specified on the boot line

2. Try recompiling your kernel with 8K stacks enabled

If you'd like to try my older Broadcom driver, I suppose I could send
it to you.  Contact me off-list if you wish to have it.
