I'm using a Sony VAIO VPCS12V9E notebook with fedora 16 installed. I just upgraded from to Kernel 3.4.9-2 to 3.6.2-1, and suspend is not working anymore . When I select suspend from the gnome menu ( or using pm-suspend), suspend doesn't work:
- the screen goes black, but does not turn off
- num Lock works,
- caps Lock works
- notebook is on, and doesn't enter suspend mode.
In this state, i can only press power button (hard power off);

I belive that suspend is not working because the acpi module was not loaded. Checking the boot log I could found the following log:
