So I tried using kernels from the PPA http://kernel.ubuntu.com/~kernel- ppa/mainline/, with the lasts "subversions" of each kernel version. Here are the things I noticed compared to the current 3.13.0-43 kernel:
linux-image-3.14.28-031428-generic, version 3.14.28-031428.201501081937 : - on first boot hanged on splash screen (I did a hard sutdown), second boot was working - resume from suspend is WORKING, but the two first times it increased the sound volume linux-image-3.15.10-031510-generic, version 3.15.10-031510.201408132333 - from this kernel to the last I tried, the graphics on splah screen are no more corrupted (usually the top half of the screen is corrupted) - from this kernel to the last I tried, the Apple logo "flashes" one time when suspending to RAM - resume from suspend is WORKING linux-image-3.16.7-031607-generic, version 3.16.7-031607.201410301735 - resume from suspend is NOT WORKING (the screen gets on briefly before shutting down again but the whole computer does not hang because I can still close the lid to suspend to RAM again) linux-image-3.17.8-031708-generic, 3.17.8-031708.201501081837 - first boot failed with a kernel panic, the next one was working. Here are messages I supposed to be interesting on this kernel panic: .............. general protection fault: 0000 [#2] SMP .............. Fixing recursive fault but reboot is needed! - resume from suspend is NOT WORKING (again, the screen gets on briefly before shutting down again but the whole computer does not hang because I can still close the lid to suspend to RAM again) linux-image-3.18.2-031802-generic, 3.18.2-031802.201501082011 - resume from suspend is WORKING linux-image-3.19.0-031900rc3-generic, 3.19.0-031900rc3.201501060135 - resume from suspend is WORKING Thanks again for your time and work, Yvan -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1406325 Title: [MacBook7,1] suspend/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1406325/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
