I have tested a few more kernels to see if we can narrow down the problem. It works on the newest 3.13.0 generic kernel, built in August, as well as the 3.19 kernel built in April.
The problem has probably been introduced somewhere on the 3.19 line between late .April and late July. I'll try to pin it down later. Platform hibernation works on the following: Linux nb-infomm-09 3.13.0-51-generic #84-Ubuntu SMP Wed Apr 15 12:08:34 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Linux nb-infomm-09 3.13.0-63-generic #103-Ubuntu SMP Fri Aug 14 21:42:59 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Linux nb-infomm-09 3.19.0-15-generic #15-Ubuntu SMP Thu Apr 16 23:32:37 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux It does not work on: Linux nb-infomm-09 3.19.0-28-generic #30-Ubuntu SMP Mon Aug 31 15:52:51 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1490494 Title: [LENOVO 80H8] hibernate/resume failure Status in linux package in Ubuntu: Incomplete Bug description: I can't resume from hibernation, as the system seems to stall after PM: Image loading is done, and non-boot CPUs are disabled. The problem appeared after I upgraded from 14.04 to 15.04. I see from the apport-summary that there is a problem with PulseAudio - could it be the cause? I've attached a picture of what my screen shows before I have to do a hard reboot. Sorry about the quality of the picture.
