I've reproduced it on a non-WEP/WPA network and WPA networks.   The real
kicker is that I can't seem to get a kernel oops even with a serial
console.  Yet the system indication (flashing caps lock) is that of a
kernel oops.  From what I can tell it has to do with receiving very
large amounts of data.  However, the amount of data alone isn't the key.
 I've spent entire days loop sending various ISOs over the link and then
pulling the ISOs without triggering it.

A thought just occurred to me.  If I'm not mistaken, this problem has
been seen with various Thinkpads with different wireless chipsets.
However, regardless of which wireless chipset the unit has they all
probably have the same sound chipset.  At least on mine, wireless and
sound share the same IRQ.  Could those of you experiencing this problem
please confirm or deny that your wireless is sharing an IRQ and what it
is sharing the IRQ with?
