Am I right in guessing that 3.1.4-1 is broken, too, and that with 3.1.5-1 the ACPI exceptions are gone? Could you attach "dmesg" output from booting a fixed kernel for reference? >From a quick glance, none of the fixes introduced by 3.1.5-1 seems to explain this change in an obvious way. Glad to hear the new kernel is working well, though.
