[Bug 417913] New: Suspend to disk freeze immediately after start
https://bugzilla.novell.com/show_bug.cgi?id=417913 Summary: Suspend to disk freeze immediately after start Product: openSUSE 11.0 Version: Final Platform: x86-64 OS/Version: openSUSE 11.0 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: leandro.gelasi@tiscali.it QAContact: qa@suse.de Found By: --- Created an attachment (id=233795) --> (https://bugzilla.novell.com/attachment.cgi?id=233795) pm-suspend.log First of all, my hardware: Fujitsu-Siemens Life Book S6410 4 GB RAM 8 GB swap space (/dev/sda8) Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03) dual booting with XP using KDE 3.5.9 Suspend to disk doesn't work: when launched it starts the hibernate screen but freeze immediately after (with a low hardware beep) I tried to disable the splash screen (splash=n in /etc/suspend.conf) and it seems that s2disk freezes immediately after starting to save the memory on the swap partition. I have to manually shutdown the notebook. When it reboots, it skip GRUB menu and go forward to boot SuSE, but (obviusly) with the standard kdm login screen. I tried to update the kernel (using kernel-default-2.6.27-rc3.3.1 from SuSE build service) and to get the latest suspend packages (suspend-0.80.20080612-6.1) with no result. s2ram works fine. Can you help me?

Can you try with a more reasonable swap partition size of, say, 4GB (or even smaller like 2G)? (I think there might be some kind of overflow with the big swap and this might help find out where the problem actually is). -- 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.

I completely reinstalled OpenSuSE (i386 version) and now I have 4 Gbyte swap area. In the first installation I created a so big swap area because I thought the problem could be that the RAM imagine doesn't fit on a 2 Gb swap. echo disk > /sys/power/state didn't work. Notebook crashed completely and I have to hard reboot it. Thanks for you help.

I explain: - launched echo core > /sys/power/pmtest - launched echo disk > /sys/power/state - correct hibernation - reboot - got the previous snapshot - click on shutdown icon, selected "suspend on disk" --> IT WORKED! Obviously that worked only that time. After a machine power off and reboot the suspend on disk didn't work anymore.

Well, the commands you gave me actually hibernate the PC, without shutting down it (electrically, I mean). The PC stops (correctly) with "System halted". Hard rebooted the notebook restart correctly with the last memory snapshot.
This is not the expected result, however, because after 'echo test > /sys/power/disk' the kernel is not supposed to create a hibernation image and it should return to the shell instead. Probably the debug mode is off in these kernels. Can you please send the output of 'cat /sys/power/disk' after writing 'test' to it? -- 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.

Well, the test mode is not supposed to do that. Please try # echo shutdown > /sys/power/disk # echo disk > /sys/power/state It should hibernate without using ACPI callbacks. If it creates an image and then it resumes successfully using that image, please check if you can repeat that reliably. if you can, please add "shutdown method = shutdown" to /etc/suspend.conf and test s2disk. -- 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.

Good news: Hibernation works reliably (tested more than 10 times). Bad news: my wireless network driver (IWL4965) doesn't work after the second hibernation/restore cycle in a row.

For the iwl4965 driver, you should create a separate bug. To make it work for you until it is fixed, see http://en.opensuse.org/Pm-utils on how to create a hook that unloads the module during suspend and reloads it after resume. -- 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.
