If I choose the option suspend2ram (in german "Ruhezustand") using KLaptop the system goes into the suspend2ram state (display off, fan off sleep LED on) if I close the display or choose "go into suspend2ram". If I open the display, only the fan wakes up, display stays dark, sleep LED stays on. This is since i did the update from FC6 to FC7.

This looks like a kernel bug to me, reassigning.
Hello Jan, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug and will try and assist you in resolving it if I can. There hasn't been much activity on this bug for a while. Could you tell me if you are still having problems with the latest kernel? If the problem no longer exists then please close this bug or I'll do so in a few days if there is no additional information lodged. Cheers Chris
Hello, I'm now running Linux 2.6.22.5-76.fc7 . The last message is stopping tasks .. done suspending console(s) ant then the system freezes. I'dont know, weather it runs in the tuxonice kernel. Cheers Jan
You might want to try the following and post back any output as attachments to this bug: # Find out if the system is locked up completely by hitting the caps lock key. * If the capslock light doesn't toggle, the system is completely dead. Try again, but this time before suspending, activate the pm_trace functionality with echo 1 > /sys/power/pm_trace. This reprograms the real time clock to contain a few bytes of information which we can use to diagnose which driver failed to resume. After the hang, reboot, boot up again, and save the output of dmesg. * If the capslock light does toggle, then the system did come back up, and it's possible that we just failed to reinitialise the video. http://people.freedesktop.org/~hughsient/quirk may contain further useful information to diagnose this problem. It may also be useful to initiate the suspend from a tty (ctrl-alt-f1) and run pm-suspend ; dmesg > dmesg.out ; sync by hand. Upon resuming you'll now have some more debug info to sift through. Additionally, this way when it resumes, you already have a console logged in from which you can type commands 'blind'. Trying vbetool post for example may bring things back to life. # Try rmmod'ing various modules before doing the suspend. If this makes things work again, retry with a smaller set of modules unloaded. Keep retrying until you narrow down which module is to blame. # Another trick that sometimes works to force video to come back up is to enable the BIOS password. This makes the system resume in a VGA text mode that the kernel recovers from a lot easier. Not a real solution, but it can help to diagnose other problems.
Hello, Did you have any success with the above? Could you attached output as text/plain from the following: # lspci -vvxxx If you are running an nvidia card with the 'nv' driver then you should not expect suspend to work as there are numerous issues with it.
Closing as per previous comment. Please re-open if this is still an issue for you.
