As reported, with 3.1-rc9 the wifi of a friend's laptop didnt work at all. With 3.0.4 it's working normally.

The problem continues with 3.1

Now I take some files for identify the problem. Below see lsmod and dmesg , and enclosed is hwinfo and syslog of that laptop as it was running with 3.1 just as wifi didn't work. For comparison, on syslog you can see the previous boots (I separated them by blank lines), all with 3.0.4 , when wifi was working.

I hope that's now enough information to fix that problem.
