Yes. It doesn't lockup now, at least it hasn't yet. Should I always configure with CONFIG_ACPI? I've usually avoided it.

I gave it a try on your advice (added nmi_watchdog=1 to boot args). No dice I'm afraid (no oops data). But I did notice in the dmesg output something possibly strange: Testing NMI watchdog ...
