Hi,
yes, it helps. i can't reproduce trap with ifconfig bridge0 after
removing stp from interfaces in bridge. But now if i destroy bridge0
after removing stp from interfaces box freeze and if in second terminal
i execute reboot i'm getting same or similar trap. i didn't try ifconfig
bridge0 destroy without this diff ..
