Ok, I'd like you to try something out: Boot into runlevel 1: you need this because you get the MCE before you've done starting apache. For that, add a "1" to your kernel command line and boot. When you get the prompt, type in your root pwd and do wrmsr 0xc001001f $(( $(rdmsr -u 0xc001001f) | (1 << 20) )) Then do rdmsr -x 0xc001001f to verify that the write has succeeded. It should say 0x00100008. then exit the prompt to continue to runlevel 2 to see whether this setting fixes your MCE issue. This is for now, thanks. -- Regards/Gruss, Boris.
