Well, it's an unrelated bug, not a variation. But that's a nit. Add to your kernel config: options CPU_CYRIX_NO_LOCK Make sure /usr/src/sys/i386/i386/initcpu.c is of version 1.5.2.5 (2.2-STABLE) or 1.10 (3.0-CURRENT) or later. The option was broken until that version. -- Matthew Hunt * Think locally, act globally. http://mph124.rh.psu.edu/~hunt/pgp.key for PGP public key 0x67203349.
