Commit 9a884ab64a4d092b4c3bf24fd9a30f7fbd4591e7 (ACPICA: Add additional
module-level code support) results in one of my test machines hanging at
boot. The last line output is:
bio: create slab <bio-0> at 0
which would normally be followed by
ACPI: EC: Look up EC in DSDT
but instead the machine hangs without printing this line. Reverting the
commit results in the machine booting. acpidump output attached.

Hi, Matthew
Could you try the attached ACPICA latest release (20091214) patch
series? There are module level code and _REG method fixes included in
it.
Checkout Linus' tree.
git am acpica-v20091214.patch
Thanks,
Lin Ming
Matthew,
Alternatively, you can pick up the latest ACPICA code from
the acpica or release branches of the acpi tree.
Please let me know as soon as you can check if it helps.
thanks,
Len Brown, Intel Open Source Technology Center

Yes, that appears to fix it. Len, could you push these ASAP?

We pushed ACPICA 20091214 in -rc1, so you should be set
with that and anything later.
