Jeffrey, I see the exact same symptoms as yourself. With 2.6.39rc4 a few times it froze completely, I waited about 3 minutes and then rebooted.
I'm unable to use Natty, it's too frustrating, I now have Maverick and Natty installed on separate partitions, as stated earlier 2.6.34 is the latest kernel that does not cause issues with Maverick. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/779753 Title: T400 laptop.
