Bug reproduced on Natty Alpha 1. There is a workaround for this now in
the upstream kernel in commit f36d83a8cb7224f45fdfa1129a616dff56479a09.
This seems to prevent a panic so is worth applying if possible, but
still causes issues.

A complete workaround is to "sudo rmmod r8187se" before using the
wireless toggle (Fn-F2) and also before standby/hibernate. Turning
wireless back on autoloads the module again.

I haven't checked the upstream build, but have tested the above commit
and have verified that there have been no other upstream changes to this
module, so I think it's safe to conclude that the panic workaround still
exists upstream but a fix does not.
