Comment 2 for bug 670787

Well, I need to explain a little more. The note above about this being a regression between kernel 2.6.31-21-generic and
2.6.35-23-generic was tested with an earlier version of Ubuntu (9.10) and this one (10.10). I tried to boot into the real time kernel from Ubuntu 10.10, which is:

frohro@frohro-D610:~$ uname -r
2.6.31-11-rt

and the issue is still there, so likely this is not a kernel issue, maybe wpa_supplicant, or something else that changed between Karmic and Maverick.
