Yeah, what was strange was that it was two of the same type of panic while running the same task in short succession. That's why I decided to send it instead of sitting on it longer. Also, it's been stable when running the buildworlds and buildkernels I've done outside of the chroot, but then those are much shorter than a gnome-upgrade.sh. There haven't been any strange signals when building things, which I would think would happen more often in a bad memory situation. I got another panic today running a 20040705 in a different part of the kernel (taking a fault while doing pmap stuff and recursing on a lockmgr lock). So maybe it is a hardware issue. Will have to stress the machine some more in different ways. -- Eric Anholt eta@lclark.edu http://people.freebsd.org/~anholt/ anholt@FreeBSD.org
