As requested, I have attached the output of the script run before

after
running 'iwlist mesh scan'. Unfortunately there seems to be no
change in
the output. I have also included the queue statistics as these do
change from
one state to the next. Any further pointers to help debug this?
I'll
gladly test
any patches that try to address this issue.
The dumps aren't correct, I had forgotten to update the script on
the website
after some API for the rt2x00 debugfs interface changes recently.
Attached is the correct patch.

<rt2x00_regdump.sh>
Fixed, new dumps are attached.
Thanks for the dumps, the reason why the beaconing isn't working
is (fortunately) very obvious from the registers point of view.
The "generate beacons" bit is simply not enabled. However the reason
why this bit has not been set escapes me. Could you apply the attached
patch? This will add extra debug messages to the driver to see when
the
beacon generation bit is set.
Thanks,
Ivo

Here are the relevant portions of the dmesg with the aforementioned
patch applied.
