Ouch. I assume this is on the machine with the AirLancer 11 - I don't
know anything about the 2Mb cards, or the state of their drivers.

Be aware that the information iwconfig gives will be misleading if the
interface is down at the time.

That's doubly weird, ok.

What would be really useful is an actual capture of the Oops message.
However that's going to be tricky since you're getting a complete
hang. As a first step could you try grabiing the latest driver
(0.09a) from http://www.ozlabs.org/people/dgibson/dldwd and seeing if
it has the same symptoms (I expect it will).

Are you using the "Linus" in-kernel PCMCIA modules, or those from the
David Hinds pcmcia-cs package?
