[Bug 395892] New: suspend to disk does not work: s2disk: atomic_snapshot result 12
https://bugzilla.novell.com/show_bug.cgi?id=395892 Summary: suspend to disk does not work: s2disk: atomic_snapshot result 12 Product: openSUSE 11.0 Version: RC 1 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Mobile Devices AssignedTo: seife@novell.com ReportedBy: mvidner@novell.com QAContact: qa@suse.de Found By: --- RC1 (build 131), the machine is Toshiba Portege 3020CT, a laptop from 2000. When I try to suspend to disk from the console, using pm-hibernate, it gracefully fails and /var/log/pm-suspend.log says "s2disk: atomic_snapshot result 12". /etc/suspend.conf has all values commented out. Interestingly, if I call "s2disk -f /var/lib/s2disk.conf" directly, from run level 1, it does work (except it does not power off at the end), including resume. I looked at http://en.opensuse.org/Pm-utils#Troubleshooting but it seems to be targetted at problems with higher layers. What logs should I look at, what debugging options are there? -- 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.

Pavel, the message is from my "increase debugging output"-patch, the code is: (in suspend_system()): if (atomic_snapshot(snapshot_fd, &in_suspend)) { error = errno; suspend_printf("%s: atomic_snapshot result %d\n", my_name, error); break; } atomic_snapshot() is: static int atomic_snapshot(int dev, int *in_suspend) { int error; error = ioctl(dev, SNAPSHOT_CREATE_IMAGE, in_suspend); if (error && errno == ENOTTY) { report_unsupported_ioctl("SNAPSHOT_CREATE_IMAGE"); error = ioctl(dev, SNAPSHOT_ATOMIC_SNAPSHOT, in_suspend); } return error; } So i guess the machine is simply out of memory, right? The same thing working from runlevel 1 is explained by less running processes etc. You might see some helpful messages in dmesg after it failed, so it might be interesting looking there. -- 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.

Hmm... we have a "great splash screen" and all the s2disk code is mlocked()... -- 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.

MB"), because anybody who is able to install on such a low memory machine will probably be able to also figure out how to optimize the suspend config ;) -- 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.
