I am now affected by this problem on 2.6.32-32-generic also. I think I have some idea as to what might be causing this:
I had installed VirtualBox when I was using 32-33. I imagine that it did something to the kernel to be able to do the functions of a Host OS on my laptop. Now, after I switched back to the 32-32, VirtualBox told me today that there were errors and I should fixed them by running: sudo /etc/init.d/vboxdrv setup Now, I have the same issue I did with 32-33 with the 32-32 kernel also. So I believe that this might be the problem. $ apt-cache policy virtualbox-4.1 virtualbox-4.1: Installed: 4.1.0-73009~Ubuntu~lucid Candidate: 4.1.0-73009~Ubuntu~lucid Version table: *** 4.1.0-73009~Ubuntu~lucid 0 500 http://download.virtualbox.org/virtualbox/debian/ lucid/contrib Packages -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/814323 Title: The laptop does not suspend anymore To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/814323/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
