suspend does not work anymore after my last apt-get upgrade on my precise Lenovo X200. I couldn't find any error messages besides:

# sudo pm-suspend
flock: 3: Bad file descriptor

There is no syslog/messages output when executing that command.

Any ideas?

This isn't a direct fix to the problem, but uswsusp may be able to provide you with alternative suspend and hibernation programs.

To install the package, run sudo apt-get install uswsusp. Run the s2ram program to suspend your computer and s2disk to hibernate. s2both can be used for hybrid suspension (similar to pm-suspend-hybrid).

More information regarding installation of uswsusp on Ubuntu is available here.
