I can't trigger the bug with 3.4.4-4.bz838004.1.fc16.x86_64 -- but for that matter, I haven't seen the backtrace mentioned in Bug 833368 ever since upgrading to 3.4.4-3.fc16.x86_64.

Comment 5 milady 2012-07-11 07:07:18 EDT
iwlwifi keeps disconnecting.
reconnection attempts fail repeatedly and eventually lead to this crash.

Package: kernel
OS Release: Fedora release 16 (Verne)
Comment 6 Dave Jones 2012-10-23 11:41:26 EDT
# Mass update to all open bugs.

Kernel 3.6.2-1.fc16 has just been pushed to updates.
This update is a significant rebase from the previous version.

Please retest with this kernel, and let us know if your problem has been fixed.

In the event that you have upgraded to a newer release and the bug you reported
is still present, please change the version field to the newest release you have
encountered the issue with.  Before doing so, please ensure you are testing the
latest kernel update in that release and attach any new and relevant information
you may have gathered.

If you are not the original bug reporter and you still experience this bug,
please file a new report, as it is possible that you may be seeing a
different problem. 
(Please don't clone this bug, a fresh bug referencing this bug in the comment is sufficient).
Comment 7 Justin M. Forbes 2012-11-14 15:29:04 EST
