Lenovo IdeaPad Z580 with Core i5. In kernel 3.5.0-17 I was able to boot with acpi=force but after upgrade to 3.5.0-23 that ability disappeared. Instead I can not boot the kernel with acpi=ht successfully.
This is for Dave Gilbert above as he requested ACPI options testing. I didn't provide my Debugging ACPI script output since I had mostly disabled ACPI. Let me know if you need anything else, I can revert and get copies of the data as needed.
