Here's my `uname -a`: =20 FreeBSD torment.storming.org 5.0-CURRENT FreeBSD 5.0-CURRENT #0: Thu Feb 6 05:11:34 BRST 2003 cseg@torment.storming.org:/usr/obj/usr/src/sys/torment i386 (Currently BRST =3D=3D GMT-2, the source tree had been cvsup'd right before the building of the kernel) =20 I'm also attaching my kernel config file, in case it should help at all.
