Aha. That is much, much better. 3.11 without radeon.dpm=1 behaves the same as 3.10; 3.11 _with_ radeon.dpm=1 quiets everything down. I don't know why it had not occurred to me it could be the fan for the radeon, not the CPUs :(. That being said, it seems like radeon.dpm=1 should be the default behavior. -- Ciao, al ---------------------------------------------------------------------- Al Stone Debian Developer E-mail: ahs3@debian.org http://www.debian.org ----------------------------------------------------------------------
