Also, have you seen any MCEs during early boot, after the freezes?

You probably wouldn't have because we don't log them on F10h due to
broken BIOSen. So add "mce=bootlog" to your grub and warm-reset your box
after one of those freezes and send me dmesg. It should have an MCE in
there, if it happens what I think it happens.
