Are you disabling the APIC or ACPI? APIC support is required for SMP,
so if you've disabled APIC, you'll not see the crash I reported.

Sorry I didn't respond earlier...
No, sorry, no actual progress on a fix. I have discovered that on my
systems, it seems related to keyboard input as/after the loader
transfers to the kernel. If I let the system autoboot, it's (usually)
fine. If I break to the loader prompt and type "boot", the boot fails.
If I type "autoboot 2", the boot succeeds. If I type "autoboot 2" and
bang on the keyboard for a few seconds, the boot fails.
I'm guessing the BIOS or loader or early kernel code somehow gets
tripped by the key-up event on the return key, which comes in after the
kernel has started. You might try some variations on this theme.
