While this is a good idea, note there may be still poisoned lines in memory that haven't resulted in a machine check yet, but could still be fatal when read after a full crash dump for some other reason. So you still need http://git.kernel.org/?p=linux/kernel/git/ak/linux-mce-2.6.git;a=commit;h=fe61906edce9e70d02481a77a617ba1397573dce and http://git.kernel.org/?p=linux/kernel/git/ak/linux-mce-2.6.git;a=commit;h=cb58f049ae6709ddbab71be199390dc6852018cd in addition. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
