I've been experiencing intermittent crashes for about 6 months on my
FE/BE combo. It ran for about 18 months without problems then out of
nowhere, it started to lock up. I've been able to determine that it
locks up when it tries to start a recoding on my PVR-350. What's
causing the crashes is still a mystery since there's no extra info in
the system logs. My system:
Asus A7N8X-E Deluxe
Athlon XP 2500
1 Gig ram
GeForce FX 5500
Firewire connected DCT6412
XFS over LVM for my myth partition.
One other thing I noticed about the time the lockups started is every
now and then (maybe every 2 weeks), I get the following error in my
Oct 22 14:33:18 pvrbox MCE: The hardware reports a non fatal,
correctable incident occurred on CPU 0.
I'm in the process of planning out a new front end and migrating to a
new backend system so figuring it out is not as pressing as it was before.
