Looks like you were right about the ACPI being disabled during boot.

I'm attaching the full logs.

Note that there are a few additions to the kernel, some are known to
everyone (kdb), and the others are self-bred facilities for tracing,
logging across kexec-invocations, and specialized memory pools
(respectively, dandalf, permamem, prebb), but these are not related
to the problem that we see here.

Just for the record, I also used a modified version of gcc 4.1.1 that
adds a switch (see the 'Re: [PATCH] add -foverride-comp-dir' thread
on gcc-devel) - it should also be completely disconnected from this
problem as well.

This kernel was also patched for retrying to mount the root dev with
a timeout, also to reduce execution time.

Sorry that I can't test with the vanilla kernel - it's a specialized
environment. All changes are available under GPL on request.
