The problem appears to be SOLVED. I commented out the last line of the fstab that mounts an nfs file share (thanks to the suggestion of user roadmr). Restarted and now after 3 attemps of suspending and hibernating worked without any problems.
Tomorrow I'll try a stress test to see if the solution is stable, using https://wiki.ubuntu.com/KernelTeam/SuspendResumeTesting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/898615 Title: [Presario C500] Hibernate command fails and returns to userspace To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/898615/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
