iwl3945 failures: Not a valid iwl3945_rxon_assoc_cmd field values
Last modified: 2010-03-26 10:54:54 EDT
After I log in to VPN, within 30 seconds, the connection goes completely dead. I cannot connect to anything new. Additionally, if I log out of the VPN, my network is still useless until I re-associate with the WAP.
% uname -r
% rpm -q iwl3945-firmware vpnc NetworkManager NetworkManager-vpnc
syslog shows these 5 lines repeating around 3 times per second until I kill the connection.

Note that this is actually not a specific VPN issue, however VPN exacerbates it. Upon further debugging whilst in Westford with Dan, it seems that the nullfunc patch from bug 493745 is not present in Fedora 11, and adding that patch seems to help so far from my limited testing.
fyi the "fix" for this is a9a6ffffd05f97e6acbdeafc595e269855829751 from wireless-testing. It works around the problem by fixing the trigger, which is the AP deauthenticating the station when the station returns from scan because the station didn't actually send the nullpacket when beginning the scan.
FWIW, that fix is in 2.6.30 since -rc1...
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.
More information and reason for this action is here:
Fedora 11 had update to 2.6.30 kernel, so that bug should be fixed.
Christopher, do you confirm that?
Ok, I assume this is fixed.
