Hello!
I bumped my RAM yesterday from 2Gb to 4Gb and ran memtest-x86
-- no errors detected (took 4+ hours).
I then booted and proceeded to use the machine. It seemed fine
for a while, until a sudden (there was nobody at the console at
the time) panic. Below.
The box runs FreeBSD 6.3-STABLE as of Thu Feb 7 on quad-Opteron
(two dual-core CPUs).
Any ideas? Thanks!
