Hello all,<br><br>I experienced a nasty system hang/freeze yesterday which I believe is related to a system update I performed on Friday evening. The hang is complete--no drive activity, Ethernet port is completely dead (router reports unreachable). As far as I can tell, the freeze happens only with MythTV, and only when I use the OpenGL painter. The system is Gentoo on kernel 3.5.7 using mostly stable packages (only a handful of keyworded ~testing packages where I need them). Hardware is Intel Sandy Bridge i3, using the built-in video (VAAPI). I generally update packages daily, and on Friday a big batch of xorg, etc. updates were released to stable, so I went ahead and installed them (see list below). After the upgrade I did a revdep-rebuild to rebuild anything with broken dependencies (there were none) and also specifically rebuilt the xf86 drivers packages that were recommended. Later I rebuilt mythtv, but it didn't fix anything.<br>
<br>I think I hadn't restarted mythfrontend since that update, and yesterday's freeze may have been a restart (not sure--the TV was off but the remote was accessible to my 4-year-old who likes to push buttons). I rebooted but it behave the same as soon as the blue background of mythwelcome appeared (nothing is written to the log before the freeze, not even a startup message). I was finally able to get it to run by forcing the qt painter, but that means I can't use VAAPI now. glxgears works correctly, but that's the extent of my other OpenGL application testing.<br>
<br>I doubt anyone will really be able to help me, but mostly I wanted to get this out there and document the problem in case someone else trips over it. A hard freeze like this has to be related to in-kernel code (i.e., the video driver). For future troubleshooting steps, I'll probably try upgrading the kernel to 3.6 and see if there's some bug fixes in the newer driver.<br>
<br>Sincerely,<br><br>Karl<br><br>Here's the mythfrontend & mythwelcome log:<br><br>Nov 18 14:12:07 [mythfrontend] I CoreContext weatherSource.cpp:424 (startUpdate) Starting update of NWS-XML<br>Nov 18 14:12:07 [mythfrontend] I CoreContext weatherSource.cpp:424 (startUpdate) Starting update of wunderground<br>
