This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig67EFFF3A43C1CDAF92F85079 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable The most recent build of FreeBSD 10.0-CURRENT crashes on one of our boxes with recent Intel hardware, see dmesg extract below. FreeBSD does obviously only crash on hardware with modern "Sandy-Bridge" hardware, the very same kernel config and a very similar setup does work very well on an older Intel Core2Dua architecture. Machine in question runs an older kernel (set via nextboot -k kernel.old) very well: FreeBSD 10.0-CURRENT #0 r237697: Thu Jun 28 11:45:08 CEST 2012 Most recent buildworls/kernels crash after going into multiuser mode (/etc/rc-scripts getting executed). Below the kernel trap message. I do this report on the fly, so if there is need for deeper investigations let me know, I will provide necessary detail requested.
