Kernel hangs during suspend and everything is block, e.g. Alt-Ctrl-F1 is not working anymore. Before it worked with kernel-desktop-3.11.10-11.1.x86_64.rpm without any problem and out-of-the-box. I analyzed the problem with https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt. In my case, it are the sound drivers, it seems to be the snd_hwdep driver. # modprobe -r snd_hda_codec_realtek snd_hda_intel snd_hda_codec snd_hwdep # echo devices > /sys/power/pm_test # echo mem > /sys/power/state works. # modprobe -r snd_hda_codec_realtek snd_hda_intel snd_hda_codec # echo devices > /sys/power/pm_test # echo mem > /sys/power/state does not work. Unfortunately, adding snd_hwdep to SUSPEND_MODULES does not work. The module cannot be unloaded, since it is used: FATAL: Module XY is in use. I've found a workaround. I unload the modules directly after startup with modprobe -r snd_hda_codec_realtek snd_hda_intel snd_hda_codec snd_hwdep in /etc/init.d/after.local, then suspend works again without any problems. Obviously, after unloading sound drivers, sound is not working anymore, but suspend is much more important to me. Reproducible: Always Actual Results: The kernel hangs/crashes/blocks/freezes during suspend. The computer has to be stopped with the hardware button. Expected Results: Suspend and resume are working. The bug report https://bugzilla.novell.com/show_bug.cgi?id=877171 may be same the problem. Since I am not sure I created a new report. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
