Hi I've been having suspend/resume issues with cgroups and this bug came up in a search I believe your problem is caused by https://bugs.launchpad.net/ubuntu/+source/libcgroup/+bug/693594
Do you have a multicore/hyperthreaded machine? If so could you try the following * Open a few root prompts * check mount for where your cgroups fs is (mine is /sys/fs/cgroup/cpu/ on previous versions of ubuntu it may be elsewhere) * In one try turning your 2nd processor off and on a few types ( e.g echo 0 > /sys/devices/system/cpu/cpu1/online ). * If that locks up use a second prompt to run (echo 950000 > /sys/fs/cgroup/cpu/sysdefault/cpu.rt_runtime_us ) if this unlocks up the processor shutdown, a suspend/resume should now work. * If suspend/resume works after putting a value in /sys/fs/cgroup/cpu/sysdefault/cpu.rt_runtime_us please mark this bug a duplicate of 693594 and look there for permanent fixes -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/590516 Title: resume hangs kernel with nouveau drivers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/590516/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
