I actually had a similar crash on my system, and it apparently was due to bad RAM modules which I've now taken out. I'll be trying to stress-test the system to see if it's stable now.
Test yours first with something like memtest86+. I was able to identify 2 separate bad memory modules with that, which was surprising to me. The Debian version of memtest86+ didn't work for me (froze during run) so I had to download from the www.memtest.org website and that one worked. My system had a kernel panic during a null pointer dereference in relation to a bad page. -- Ryan Thoryk r...@thoryk.com r...@tliquest.net
