SVN13445: Frontend crash on LiveTV -> Menu -> Guide [incl. backtrace]

Reported by: Jon Whitear <jon@…> Owned by: Isaac Richards
Priority: minor Milestone: 0.21
Component: mythtv Version: head
Severity: medium Keywords:
Cc: Ticket locked: no


I'm running r13445 on a separate frontend/backend setup. On the frontend, when I'm watching LiveTV, bring up the on screen menu, and select "program guide" the menu disappears and the video freezes. This happens maybe 1 in ten tries. This system has no keyboard/mouse, so I have to reset it to clear the problem.

I have attached a backtrace per the documentation. Myth is compiled with --enable-proc-opt:

fe1 mythtv # ./configure --prev Options: --enable-proc-opt --enable-xvmc --enable-opengl-vsync --compile-type=debug # Basic Settings Compile type debug Compiler cache no DistCC no Install prefix /usr/local CPU x86_64 (AMD Athlon(tm) 64 Processor 3500+) big-endian no MMX enabled yes

I think this is related to using a configured GUI size to compensate for overscan. I had the GUI set to 1170x670 with a 30x30 offset (IIRC) and this freeze was fairly requent. I have now removed those settings (set them to zero) and I haven't had this freeze for a couple of days.

I agree with Jon's comments about it being related to the GUI width in the Appearance setup. X is setup for 720x480. I normally run the GUI at 656x460 due to overscan issues. When I set them to 0x0, there are no crashes.

I don't see a segfault but rather a complete system halt. I'd suggest this is nvidia bailing-out and taking the kernel with it.

This looks like a driver problem from the backtrace. There were some problems unorthodox GUI sizes as well, as commented upon here, but I committed fixes for those problems a while back.
