Is this a regression?  (E.g., does the squeeze kernel behave the same
way?)

Yeah, sounds like nothing good.

Your best bet is probably to contact linux-acpi@vger.kernel.org,
attaching "dmesg" and "acpidump" output.  If doing so, please cc
either me or this bug log so we can track it.

Thanks for a clear report.

Sincerely,
