This is the WARN_ON in question (inside __ieee80211_scan_completed):
if (!was_hw_scan) {
bool on_oper_chan2;
ieee80211_configure_filter(local);
drv_sw_scan_complete(local);
on_oper_chan2 = ieee80211_cfg_on_oper_channel(local);
/* We should always be on-channel at this point. */
WARN_ON(!on_oper_chan2);
if (on_oper_chan2 && (on_oper_chan != on_oper_chan2))
enable_beacons = true;
ieee80211_offchannel_return(local, enable_beacons, true);
}
Uh, I forgot about that. In 3.2 there is no revert of off-channel optimization, which we applied in fedora:
> http://pkgs.fedoraproject.org/gitweb/?p=kernel.git;a=commit;h=67de50b811ecec877c8ca1a9309f0567141b9269
And which should fix that warrning.
We currently discuss how to do that revert in 3.2-stable, as there are differences between upstream commit and that patch...
Test kernels w/ Stanislaw's revert patch are building here: http://koji.fedoraproject.org/koji/taskinfo?taskID=3641961 Please try to recreate the issue with those kernels when they finish building, and post the results here...thanks! An equivalent patch has just been applied to f16... *** This bug has been marked as a duplicate of bug 773271 *** |
