[mythtv-users] Machine hangs, poss. because of PVR-250

   Why the PVR-250? Why not the Firewire? The shuttle MB? Even memory
could be a cause here. What about generic overheating?

   If it really crashes this often then I'd do this:

1) Reboot without loading ivtv at all. Let it run for a day. Any crash?

2) If it crashes with the PVR-250 in but ivtv not loaded then remove
the PVR-250 from the machine and run for another day. Any more

   If you go at it one step at a time eventually the real root cause
will appear. More often than not, in my experience, these problems are
caused by the motherboard or memory. Run memtest86 for 6 hours and see
what happens.

Good luck,

I can't see anything blatant in the logs that might be causing this to happen. Logging just stops, in dmesg and the other system logfiles.

The ivtv list seemed to indicate that there's a problem with DMA in the 0.3 versions and thus I though that downgrading ivtv from the 0.3.x version (in at-testing) might help, but that doesn't seem to have done the trick.
