Gerry has this right - we want to preserve the error information, but we
don't trust our kernel enough to have it write to a regular disk (perhaps
it has no access to I/O because of the error - or worse, perhaps it might
write to the wrong place or the wrong disk).
In theory data the information in the machine check banks is preserved
across a warm reset for the reboot - but in practice we may sometimes
need a power-cycle and full cold reset. Also I've heard that on some systems
the BIOS clears the banks before the OS can see them.
