Comment (by warpme@…):

 Daniel, I managed to get trace+log on vanilla [d3a5b0a]. Scenario was
 following:[[BR]]

 1.start BE, wait till active EIT starts[[BR]]

 2.created manual schedulle on tuner doing EIT[[BR]]

 3.FE rec. list shows that recording starts but reported size was 0 during
 3 min[[BR]]

 4.killed ongoing recording, wait 1min[[BR]]

 5.schedulled again new recording on this tuner[[BR]]

 6.when recording should start - BE deadlocks[[BR]]


 Observing correlation between BE & FE I see that recorder starts but not
 writing. It looks like it is blocked by previously working EIT scanner on
 this tuner. Scheduling another recording on this blocked tuner deadlocks
 BE. Log + trace attached.
