Bug Description
Suspend to ram stopped working after updating to karmic. Either selecting suspend in the shut down menu, closing the lid or running pm-suspend has the same effect: network is disconected, hd activity is like system is going to suspend and then network is connected again and the system keeps running: seems like a resume immediatly after suspend.
Screen does not blink or go black. Note that it is running in karmic's default kernel mode switching (KMS).
Seems to be similar to bug #426906, but in my case it do not work with 2.6.31-9 either.
I am attaching pm-suspend.log.

Definitively it should be a kernel issue since booting with my old Jaunty kernel solves the problem:
$ uname -a
Linux netbook 2.6.28-15-generic #49-Ubuntu SMP Tue Aug 18 18:40:08 UTC 2009 i686 GNU/Linux
with this kernel I do not have kernel mode switching as expected.
At the same time, a minor issue with brightness control has solved and USB devices works again (they stopped working with karmic as well), although these should be reported as a different bug.
