does your machine crash with "panic: unexpected machine check", or
"panic: fatal machine check or error (unknown type)"?

It turns out that i disable correctable error reporting, so it
shouldn't be seeing machine check interrupts for correctable errors.
(I forgot about this earlier.)

It could be that disabling correctable error reporting turns
correctable errors into "real" machine checks somehow, but if so
that's not documented (that i'm aware of).

It'd probably make sense to enable correctable errors and print out
what i can about them, when they happen...
