Issue with iwlwifi cards

["Darren Albers" <dalbers gmail com>]

I recently purchased a new laptop with an Intel IWL4965 card, the
iwlwifi drivers work well except I seem to lose my connection after
around an hour of use.    For the heck of it I tried connecting with
NM stopped and just ran wpa_supplicant and my connection remained
stable.   I then ran NetworkManager --no-daemon and got this error
after about 30-40 minutes and my connection dropped ~ 5 minutes later:

*** stack smashing detected ***: /sbin/wpa_supplicant terminated

The strange thing is that NM thinks I am still associated...

When I click on nm-applet and tell it to connect back to my AP it
connects fine and this is the output:

There is an open bug report for this issue on intel's bughost at
http://bughost.org/bugzilla/show_bug.cgi?id=1360 but I am beginning to
wonder if this might be a NM (or possibly a Gutsy specific issue?)

I am running Ubuntu 7.10 (Gutsy) with Network Manager 6.5 with a
IWL4965 wireless NIC on a Lenovo T61.

This list had been quiet for a few days so I figured it was time to
drop a message  ;-)

Thanks!
