Viktor Pal, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please provide the information following https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume ? As well, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . However, note you can only test Suspend, not Hibernate, when using a LiveCD. If the issue remains, run the following command in the development release from a Terminal (Applications->Accessories->Terminal) as it will automatically gather and attach updated debug information to this report.
apport-collect -p linux <BUGNUMBER> Additionally, if you could try to reproduce this with the upstream mainline kernel that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream-testing' text. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Please let us know your results. Thanks in advance. ** Tags added: needs-upstream-testing ** 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 + WORKAROUND: I have used uswsusp instead of the hibernation integrated + into the kernel and it is very reliable. There is no error, it always + recovers from hibernation.
