A little background: [1]

Is this a regression?  (I.e., did earlier kernels behave differently?)

Please attach full "dmesg" output from booting and "acpidump" output.
If you get a chance to try v3.2-rc7 from experimental, that would be
interesting, too.

Thanks for a pleasant report.

Ciao,
Jonathan
