Thanks.  Please try to reproduce it in recovery mode --- in that
mode there is no display manager.  If you can reproduce the hang
with a 3.7.x or newer kernel from experimental, that would be best
since then we can get help from upstream.

You can also get some information about wifi events by running "iw
event -t" with output redirected to a file and examining that file
after rebooting.

I assume that in the hanged state the magic sysrq key doesn't work?
