I run F16 on my desktop computer. I've been using suspend for years, but after some 200+ megas of package updates a couple of days ago, suspending works, but it's resumed automatically immediately.
pm-suspend.log says all is fine and dmesg lists a successful suspend procedure followed immediately by a successful resuming.
I use nvidia proprietary drivers from rpmfusion.
Most of the hardware is years old, so it's not impossible that for example the power supply is beraking down. Awfully nice coincidence, though that this started just after the update. I think I shut down the system after the update was finished.
Any helpful ideas?
