I encounter some problem after upgrade from F10 on the Dell Latitude D620.
1. Power meter not detect power condition properly, when power pulled off, still show connected
2. switch display not working, I have the similar problem in F10, but I can work around the problem with xrandr, but in F11, this workaround is not working also.
3. sleep/hibernate not coming back. in F10, both sleep/hibernate is working perfectly, but in F11, both are broken, sometime it may come back, but most of time I have to hard reset the laptop.
