** Description changed: I'm not sure if this is actually a pm-utils or a kernel bug. So what happens is that after I hibernate my Laptop it does not recover in about 50% of the cases. During the recovery it simply unexpectedly restarts. Of course during this restart it does not enter the recovery phase again. This is the laptop model: http://www.ubuntu.com/certification/hardware/201012-6932:201101-7008 The last entries from syslog (the entries before the entries of normal start): Oct 26 09:13:24 desktop kernel: [37911.699784] EXT4-fs (dm-1): re-mounted.

So the recovery does not generate entries in syslog during the recovery. That's really annoying. I can't rely on hibernation although I really would need it. I bought this laptop because it is Ubuntu certified :) I see this on the above mentioned page: Hibernate is disabled on this system But does it mean that it will never be supported on this system? Could someone help me in how to debug this to be able to gather more information? If it's something I can correct I'm willing to do this., at least try. + I have used this documentation to debug this: + http://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt + + The test hangs when running it with this setting: + echo processors > /sys/power/pm_test + + ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: pm-utils 1.4.1-8ubuntu1 ProcVersionSignature: Ubuntu 3.0.0-12.20-generic 3.0.4 Uname: Linux 3.0.0-12-generic x86_64 ApportVersion: 1.23-0ubuntu3 Architecture: amd64 Date: Wed Oct 26 19:19:48 2011 InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111011) PackageArchitecture: all - SourcePackage: pm-utils + SourcePackage: linux-meta UpgradeStatus: No upgrade log present (probably fresh install)
