Subject: [REGRESSION] 9a884ab64a4d092b4c3bf24fd9a30f7fbd4591e7 causes boot
	hang

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.
