This seems like it might be hardware specific, I am running on a Lenovo T520, running bios version 1.42, firmware rev 1.36. This seems to be limited to x86_64, as i386 does boot. I build my initram into the kernel image, the following boot line triggers the issue. The issue causes no kernel messages to be printed to screen (looks like the kernel isn't loading at all to my untrained eye= s). linux /kernel-3.9.7 mem=3D300M the following link contains kernel images and vmlinux for both amd64 and the referenced kernel versions http://dev.gentoo.org/~prometheanfire/bugs/471626/ we are tracking the bug here (keep in mind, this is NOT a pax bug) https://bugs.gentoo.org/show_bug.cgi?id=3D471626 I have tested the following combinations. amd64 - 300M - 3.9.7 - bug hit amd64 - 300M - 3.10-rc7 - big hit amd64 - 16G - 3.9.7 - bug not hit amd64 - 16G - 3.10-rc7 - bug not hit i386 - 300M - 3.9.7 - bug not hit i386 - 300M - 3.10-rc7 - other bug possibly hit i386 - 16G - 3.9.7 - bug not hit i386 - 16G - 3.10-rc7 - other bug possibly hit the pictures taken for the other possible bug hit are located at http://goo.gl/741ub --=20 -- Matthew Thode (prometheanfire) ------enig2UPCERNTLQCXCKTWSPJRN Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.20 (GNU/Linux) iQIcBAEBAgAGBQJRzGy/AAoJECRx6z5ArFrDFjkP/jFRdlVKvtx5wFpd4/JDsafr Hvk3p6+yKHgVlYUYxAyhXbfoAptkEmF9XVh2zmXjEk5AkA0WS1AJerqe1rcsrxdK FWGwCkC216WLW0tSWXgAsMqDis2pOX3aFMta09yoWbWIw/an39QqfjEr3AX4sWGs CLTTdned8zOZQliyzuL2uG23FOp9Is++ns3So7Txo4646X2b7GX3g7Pe7PghVIX+ 6Tg/UNTmXueW5YY5XAWHeadw6TC3340PAijqbQE1opiPJGHUd+hEdbbJTZ0RGall QxQb5Jqvvd6VmldzHSjUH5CZsZEEHgIdVgRtkULYZi3eSssc+wbnpbTBxWw6qAIq rRdrNIZfbsoC5l4IbShwZrN3pgoIm4f84rwOzWXBEuzkIdauhVSou+vObfHzgnkF qYT9W8hvc376ZHhEDGzAOALziCEbNdjmKIhyU6Xa3ItjMjPdGOZ5f76nEn7S5oMn 0ZXG/ERuoqRhV1P+rE5o1sN87hHN8Hy/zseIiD1J6ibQstZP3yq7cYSDxvKwPMtq /B+MKvbR80q4N6aeHhtJAhQDkAbHk8vu/7+vtUnebC+2akL4k95XtmntKPROZeQm tlVwhioKyMnc/nGasD6pfZVaGjqO1x7d4y8tCZAqtV6dxjGQ028g0quZwP0bqlHJ wR4x5eb0H+duf3n9ceqR =0lS/ -----END PGP SIGNATURE----- ------enig2UPCERNTLQCXCKTWSPJRN--
