next in thread | raw e-mail | index | archive | help
I've been experiencing crashes across several updates now
since around 4.6-RELEASE. As this is my first attempt to really
debug a problem like this, I'm hoping for a little help from the
community in how to go about such a thing. I'm not running a
kernel with debugging turned on yet, because I don't want to
stomp on anything which I might could use at this point to
analyze the crash dump I have. So that might be something I need
to do before anything else really. This is what I have so far:

This machine serves mostly as a(n) NFS server for ten
Linux machines (running Debian/testing and 2.4.19). It has less
than half a dozen interactive logins going at any one time
usually, and those are usually mutt/pine or irc sessions inside
of screen. That's really about it.
Any ideas or suggestions? If the trap above is accurate
(page fault while in kernel mode), is it similar to many of the
cases before on this list of misbehaving hardware?
