gdb.2.txt is a duplicate of gdb.txt and can be ignored. The freeze happened at 10:00. This may just be residual of the earlier pvr-350 freeze fixes, but I thought I'd at least post it.

(In [8866]) Fix a race condition (was confused about where it was in the chain during a smooth transition between shows)

Probably fixes #942, #971, #1213, and any other 'livetv breaks at end of a show' issue.

So, with 42 seconds left in the Super Bowl, this issue occurred again with svn 8873. At 10 pm the program was scheduled to change, and the frontend locked up. Attaching gdb trace and backend log. I wasn't able to get the frontend log.

I've been following this bug for some time now. This still happens for me every day at least once. I'm on a PVR150, ivtv 0.7.0, kernel 2.6.17 (gentoo), and am running 0.20 fixes, svn-11497. I will attach a frontend log, in which I see the conspicuous:

Frontend log *from a pvr-350 user*, as the bug title says.
