[Bug 1218762] [NEW] iwconfig crashes computer

[Oscar Tiderman]

Public bug reported:

Everytime I try to run 'sudo iwconfig' the pc just crashes and hangs
with caps lock light flashing, I believe this is a kernel krash.
/var/log/syslog contains no traces of the crash. I have seen several
reports for this behaviour on Mac, and I believe they are also on
Broadcom drivers, so that is probably the lowest common denominator.
