The ACPI code definitely _triggers_ it. However, if you bisect, I bet
you'll just bisect down to the new debugging check that you're hitting:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a25b9316841c5afa226f8f70a457861b35276a92
So, if you're able to bisect it, you'll need to apply that patch
whenever you're at a bisect point _before_ it was applied. That might
also mean doing some merging because I'm sure the code around there has
changed. IOW, bisecting isn't going to be super-easy.
