Since I upgraded my Dell E4200 laptop to Fedora 15, I have had some problem
with suspend/resume: occasionaly, the computer would freeze on resume.
(I suspend by pressing fn-F1. My power manager is the kde plasmoid. I am not

Most of the times when it happens, it freezes before leaving anything

WARNING: and a BUG: in the log.
The computer was working fine with Fedora 14, and is working fine while

displays an empty battery for about one second before displaying the correct
