FWIW, My issue was I had a redhat-release file in /etc, which I've created some times ago in order to make some work scripts targeted to RHEL 4 work.
Deleting this file fixed this issue for me. It was a bit hard to debug given the lack of error reporting from hal. It should write a log entry on script failures. -- Wont suspend (or hibernate), won't say why, and is annoying. https://launchpad.net/bugs/50785 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
