Yeah, your system should not even be trying to invoke pm-pmu (I assume that is what you meant -- afaik, there is no power-pmu command), but for whatever reason the binary seems to be installed on your system.
The attached patch should work around it. Could you also attach the output of the following commands to this bug report? dpkg-query -S pm-pmu ** Attachment added: "Better pm-pmu checking." http://launchpadlibrarian.net/13079595/pm-pmu.patch -- pm-suspend.log reports "power-pmu: failed to open /dev/pmu" https://bugs.launchpad.net/bugs/210832 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
