This command means that mac80211 uses the start() callback function. This triggers rt2x00 to initialize
the registers which resets the beacon generation.

Strange, that doesn't seem right. If you look at net/mac80211/ iface.c,
you'll see it call ->start(), then ->add_interface(), and later
ieee80211_start_mesh(), which calls _if_config() and sets
beacon/beacon_enabled.

ok, I gone through the rt2x00 code a couple of times now to see how this bug can be triggered by rt2x00, But the only other scenario I could find, is when the open() callback for the netdevice structure doesn't end with a call to the config() callback function. But as far as I see it that is happening correctly.

Maybe log (+dump_stack()) all the relevant calls from mac80211 to the
driver? That might give us a better idea of what's going on. Also,
Antonio, make sure you're using the very latest code. I for one need
sleep now :)

Antonio, could you please use attached patch to add additional debugging to rt2x00. This will do a dump_stack for all important functions (add_interface, remove_interface, config() and config_interface())

It doesn't matter if this patch is on top of the previous patch or not.

Thanks,

Ivo
<debug.diff>

Ok, I have updated to the very latest code (still the same behaviour though) and applied the new patch. The rather lengthy list of backtraces is attached.
