I don't seem to have any problem with my T42p using a kernel compiled on 11/29 11:21 My copy of if_em.c is: /*$FreeBSD: src/sys/dev/em/if_em.c,v 1.65.2.8 2005/11/25 14:11:59 glebius Exp $*/ g. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
