They're not in the kernel log if it's an MCE that causes the kernel to declare a panic. There's some MCE's that you can retry the operation and continue, and some that you can get away with poisoning a page, killing the process, and rest of the system is OK. But some you really need to roll over and die because you can't guarantee kernel integrity anymore. And at that point, those messages are never gonna make it to syslogd and onto disk. --==_Exmh_1317830438_2599P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFOjH8mcC3lWbTT17ARAgaLAKCFRXcqzTLI6xyllyVLc2NRAaLgVgCeMzDi ukG1PwIQuODnxVXi/GOKe/0= =4gHJ -----END PGP SIGNATURE----- --==_Exmh_1317830438_2599P--
