2012-05-05 09:11:16 Thomas Schlichter tags regression-release apport-collected precise regression-release
2012-05-05 09:11:17 Thomas Schlichter description On my Samsung NC20 Netbook the BIOS hides the C3 C-state when the AC power is connected, but it should show up and work as soon as the AC power is disconnected. This expected behavior worked fine as long as I used Oneiric. But now I upgraded to Precise and now C3 does not work anymore after disconnecting the AC power. I have verified, that booting the Oneiric kernel 3.0.0-19.33 instead of the Precise Kernel 3.2.0-24.37 (same userspace) fixes the problem. To gather some information, I executed this command with the Precise kernel grep -r "" /sys/devices/system/cpu/cpu0/cpuidle/ in different system states: 1. newly booted without having the AC power attached 2. having the AC power attached (without C3, as expected) 3. now after having the AC power disconnected (not functional C3 --> bug) The output is combined in the attached file "cpuidle.txt".
