Hi all -
I saw this while booting 2.6.30-rc1, -rc2, and today's git, on one of
my development nodes. This output is with apic=debug. With noapic,
it still hung. Both outputs follow.
git bisect leads to commit 8d6f0c8214928f7c5083dd54ecb69c5d615b516e,
but I'm not seeing anything obvious there. Backing just that change
out doesn't fix it.
