Re: Same MCE on 4 working machines (was Re: Early boot hang on recent 2.6 kernels (> 2.6.3), on x86-64 with 16gb of RAM)

Ooops, I'm sorry, I didn't actually follow your instructions; all
the testing I just did was with Debian's 2.6.8-12-amd64-k8-smp. Too many
kernels on the box; I'll re-image.

Installing my own 2.6.17.11 now.

The behaviour is a bit different on my own 2.6.17.11; no idea why,
haven't compared the configs carefully yet. Instead of having the
MCE, it hangs at:

- --------------------

CPU 0: aperture @ 0 size 64 MB

Note that that's the *first* CPU; it doesn't even get to the second
one.

If I use acpi=off, if gets to the MCE:

- ---------------------

"mce=bootlog" has the same hang as the first case above.

"mce=bootlog acpi=off" has the same MCE as the second case above.
Specifically:
