rtl8192se: regression in linux kernel 3.3.5
Last modified: 2012-06-22 04:37:38 EDT
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:

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:
Created an attachment (id=73319) [details]
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:
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?
