Issue: when user is changing LiveTV to channel on which current program just ends, it is easy to deadlock BE. Severity of this issue is higher than You may think. Many users are starting zapping around full quarters/halves/full hours (xx:00, xx:30, xx:15[45]) as broadcasters usually are emitting commercials end of current program - so user zaps to another channel just to not watch commercials which begins. If zap to new channel is zap channel where current program also ends - BE will deadlock. Very unpleasant. I have reports of this issue from many users using LiveTV frequently. Steeps to reproduce: -start LiveTV -identify another channel where program will just end, let say at xx:yy -wait till few sec. before xx:yy and jump to this another channel -it is highly probable that after jump BE will deadlock Easy way to reproduce is: start LiveTV; browse EPG OSD in LiveTV to find channel with end time nearest to current time; wait till this time; Just few sec.before this time jump to this channel; BE will deadlock I'm attaching BE logs and BE gdb traces from 2 such deadlocks. 1st was during normal zapping; second was reproduced for getting gdb trace for this ticket ",Bug Report - Hang/Deadlock,closed,major,29.2,MythTV - General,Master Head,medium,Trac EOL,LiveTV,,0
