(In reply to comment #0) > Version-Release number of selected component (if applicable): > kernel-3.6.10-4.fc18.i686 I was able to reproduce this on 3.6.6-4.fc18, but not on updated 3.6.10-4.fc18, (which include fix for very similar bug 883414). Are you sure you run test on new kernel?
I retested with updated system (kernel-3.6.11-3.fc18). The only change I noticed the nm hotspot mode now use adhoc network mode (I think it previously used infrastructure, but I am not sure). In adhoc mode with kernel-3.6.11-3 everything worked as expected. When switched to infrastracture the same problem appear.
It's yet another problem, we do not correctly change interface type when switching back from IBSS to STA mode.
Created attachment 679466 [details] 0001-iwlegacy-fix-IBSS-cleanup.patch Fix for this problem, tested by myself.
Josh, please apply above patch as fix for this bug. I just posted it upstream and cc -stable too.
Applied on all branches. Thanks!
