[mythtv-users] OT. Howto diagnose machine dying/crashing

[Tim Berger]

Let me take a wild guess - you're using xfs, aren't you?

There's going to be a lot of people on this list with high praise for xfs,
but on a 2.6 kernel with 4k stacks, there's a high likelihood of oopsing the
kernel, especially when layered with raid and nfs.  ext3 works just fine
with myth, and it's *stable*.

In any event, netdump is a great tool to capture an entire oops message with
these sort of lockups, if it indeed it's oopsing.
