If you don't use fancontrol and that just switch from kernel 3.12 to 3.13 causes this issue, it is definitely a kernel issue. It is very likely to be the following upstream bug: https://bugzilla.kernel.org/show_bug.cgi?id=71711 I am therefore reassigning the bug to the linux package. -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurel...@aurel32.net http://www.aurel32.net -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
