I've been encountering a very weird suspension problem on my T61 with Fedora 10 installed. After I put it to sleep by Fn+F4, I have to wake it up three times before it really 'wakes up'. For the first two times, the computer seems to be waking up and the login screen flash for a fraction of a second. Before anyone can react, the system goes to sleep again and I have to wake it up for another 2 times and eventually it will work. This doesn't happen if the computer is put to sleep for a very long period of time (say 10 hours). Anyone experienced the same problem? Thanks.
