after upgrading today the kernel is: 2.6.32-21-generic #31
I booted with the no_console_suspend option as described in the link of comment #47.
after entering command pm-suspend, it took 40 sec until this 2-line message came up:
[ ] Freezing of tasks failed after 20.00 seconds (1 tasks refusing to freeze):
[ ] gvfsd-trash
I entered pm-hibernate, and also after 40sec the very same message came up
