Suspend to Ram works fine on vanilla 3.8.x. I tried 'pm-suspend --quirk-save-pci' and that locked up on resume (13 minutes and no activity). I then remembered something Thomas said (see Thomas, my head is not *completely* full of hot air) and ran this: [root@rhelrt-7 ~]# for i in core processors platform devices freezer > do > echo $i > echo $i > /sys/power/pm_test > pm-suspend > done core processors platform devices freezer [root@rhelrt-7 ~]#=20 So all the pm_test modes passed.=20 I replaced the nVidia adapter with an ATI Rage card I had laying around and that did not change the behaviour noted previously (i.e. pause of nearly 10 minutes on resume). So, something is wedged in the resume code and times out after nearly 10 minutes and lets the resume continue. I think I'm going to have to take a long stroll through the resume path code and look for likely candidates.=20 Debugging suggestions welcome.
