Description of problem: After upgrade kernel to 3.3.5 my wi-fi doesn't work. iwlist scanning works fine, show available networks, but network-manager can not connect any network. I try to reboot back to 3.3.4 - on 3.3.4 all works fine. Version-Release number of selected component (if applicable): It is lines from dmesg: [ 11.085728] rtl8192se: rtl8192ce: FW Power Save off (module option) [ 11.085967] rtl8192se: Driver for Realtek RTL8192SE/RTL8191SE [ 11.085969] Loading firmware rtlwifi/rtl8192sefw.bin oleg (0) /external/video$ sudo ethtool -i wlan0 driver: rtl8192se version: 3.3.4-3.fc16.x86_64 firmware-version: N/A bus-info: 0000:03:00.0 supports-statistics: no supports-test: no supports-eeprom-access: no supports-register-dump: no oleg (0) /external/video$ sudo iwconfig em1 no wireless extensions. lo no wireless extensions. wlan0 IEEE 802.11bgn ESSID:"DIR-300NRU" Mode:Managed Frequency:2.437 GHz Access Point: B8:A3:86:BA:D6:48 Bit Rate=54 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:on Link Quality=70/70 Signal level=-35 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:168 Missed beacon:0 oleg (0) /external/video$ I also filled bug on kernel.org: https://bugzilla.kernel.org/show_bug.cgi?id=43253
Please, freeze 3.3.4 version OR backport following patch: https://bugzilla.kernel.org/show_bug.cgi?id=43253 Created an attachment (id=73319) [details] Probable fix This patch, which has just been merged with kernel 3.4-rc7+, fixes a racy condition associated with asynchronous firmware loading. The main difference for rtlwifi and friends between 3.3.4 and 3.3.5 is the switch from synchronous to asynch. firmware loading that is necessary due to changes in udev. This patch will be backported to 3.3.X, and may be in 3.3.6.
This missed 3.3.6 but should be in 3.3.7. We'll look at backporting it in the meantime.
Oleg, could you test this scratch build when it completes: http://koji.fedoraproject.org/koji/taskinfo?taskID=4083807 It contains a backport of that patch.
Ok, will test and provide feedback.
All works fine, thank you. When 3.3.6 will be in the fedora 16? Or I should get fedora 17?

It was submitted as an update earlier, but the version submitted doesn't include this patch. The bodhi update system will leave a comment in this bug when it is available in an updates repository.
Thanks for your feedback and great quick job! Will wait robot comment :)
