Update to my previous post (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/226279/comments/113 ): This morning, there were a number of items related to kernel 2.6.24-19-generic in my automated Update Manager list. I'm not sure which repository they were from (hardy-proposed or a more regular repository). I told the system to download and install all the updated. Oddly, there was no automated request to restart the computer. I restarted anyway, using the 2.6.24-19-generic entry in GRUB. Same result as before, though: Suspend/Resume does not work. Hibernate works but very slowly (not sure if there is a real advantage compared to full Shutdown/restart).

Kernel 2.6.20-16-generic allows me to Resume from both Suspend and Hibernate, but again very slowly: see my post at https:/ /bugs.launchpad .net/ubuntu/ +source/ linux/+ bug/221213/ comments/ 18
