I know this isn't exactly what you're looking for, but I have a CD (actually, a GameCD beta) available at http://dev.gentoo.org/~wolf31o2/x86-ut2004demo-20040420.iso that you could grab. It has only one kernel, and it is SMP. It has booted and worked successfully on every machine I have tried it on, and even has X+fluxbox on it. > I had no lockup problems while running that kernel, but after rebooting=20 > with my kernel (gentoo-sources, built with Chris's=20 > CFLAGS=3D"-march=3Dpentium4 -O2 -pipe -fomit-frame-pointer") I've already= =20 > suffered two lockups.

Copy the kernel from my CD and the /lib/modules/2.6.5-gentoo-r1 and see if that kernel works fine on your machine in your build environment. > Something very weird here.

That will help test some of the problems, especially since the kernel you are "testing" with is not SMP, so you're not really testing anything. > Does anyone think that my two CPUs having different stepping levels could= =20 > have anything to do with this problem? One is level 7 and the other 9. It is possible that is causing the problem. You never really know.

It still could be bad memory. I think I would trust memtest86 before the Dell utilities. You could also try finding another bootable system checker. I'm sure there are plenty available. --=20 Chris Gianelloni Developer, Gentoo Linux Games Team Is your power animal a penguin? --=-5dhJAK1k/pdjjpnH3zLG Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQBAo3J2kT4lNIS36YERAlJvAJ4nkgvX2hqyhoY6o67rz4NLNXAmHACfWNgL BnKe1WBC3djGYe3MMHyS8VY= =ojOq -----END PGP SIGNATURE----- --=-5dhJAK1k/pdjjpnH3zLG--
