Maybe I'm doing something wrong here.
I run mcelog from the shell after the boot.
Nothing happens, I get the shell prompt right back.
How do I know it's really a MCE? So far my symptoms are: the machine
freezes, then a panic dump scrolls by, and the only text I can see on my
screen are the stack dump lines, which contain something to the tune of
machine_check() or so. Nothing shows up in syslog, probably the kernel
decides the box is too hosed to log anything.
