The second core does go to 100% CPU frequency on resume. Top reports no load on the system and /proc/interrupts looks fairly evenly balanced between the cores. It seems that /sys/devices/system/cpu/cpu1/cpufreq not being there makes powernowd unhappy though:
# /etc/init.d/powernowd restart * Stopping powernowd: [ OK ] * Starting powernowd... /etc/init.d/powernowd: 175: cannot create /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor: Directory nonexistent [fail] -- Second CPU core loses frequency scaling on resume https://bugs.launchpad.net/bugs/192300 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
