Your usual vmlinux is almost certainly linked to load at the 1M line, and you need a kernel linked to load at the 16M line (as set in crashkernel=). See the CONFIG_PHYSICAL_START config option, and there's other details in Documentation/kdump/kdump.txt - it looks like you have most of it right, except you need to build *TWO* specially configured kernels (your production one with KEXEC support and a few other things, and then the dump kernel with a different PHYSICAL_START and a few settings). --==_Exmh_1159933617_3990P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFFIy6xcC3lWbTT17ARAj6NAJ99YRx2xKN2RS8gkYFq0TMB4X+YHQCePO38 wXS6Jk/CG0bbyx6KveJK3lM= =mvgd -----END PGP SIGNATURE----- --==_Exmh_1159933617_3990P-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
