Comment 31 for bug 717919

Also tried the most recent nightly build from linus' tree:

Linux elrond 3.2.0-999-generic #201112250405 SMP Sun Dec 25 09:13:50 UTC 2011 i686 i686 i386 GNU/Linux

Result is the same:

Btw: how do I have to use to tool powertop to get the form "Top causes for wakeups"?

dmesg does not show any more information after booting
