Hi Christopher, I installed 3.18-vivid from http://kernel.ubuntu.com/~kernel- ppa/mainline/v3.18-vivid/, and the results are concerning:
First I rebooted and booted fine into 3.18. I run "uname -a" just to be sure, and listed 3.18 as the current kernel. Of course I didn't have wifi with 3.18, so I wanted to reboot to go back to 3.13.43. Upon reboot I pushed "del" to make grub show its menu, chose 3.43 and then it got stuck with a blinking cursor. So I shut down the machine, booted again and letting it go into 3.18: this time it dit NOT boot, to my surprise. I would appreciate help in understanding what had changed. Upon reboot using the "failsafe" option, I saw that the booting process got stuck at SMP #1. So I shutdown, rebooted and edited the grub kernel options to include the "nosmp" flag, and that booted into 3.18 just fine --from which I am writing this (via USB-ethernet). Haven't tested yet if the thunderbolt ethernet and suspend work. Before I engage into further reboots that could get stuck, I would appreciate assistance in understanding why the second time 3.18 needed the "nosmp" flag, and how can this be addressed. Additionally I would appreciate help in understanding why grub cannot boot the old 3.13.43 kernel when chosen from the grub menu. I recall this issue when I first installed Ubuntu into thhis macbook pro 11,1: only the default menu option would boot from grub; choosing from the list of available kernels did not work, likely because of the SMP issue. Thanks in advance for your insight. -- 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/1371159 Title: [MacBookPro11,1] Unable to suspend in ubuntu 14.04 Status in linux package in Ubuntu: Incomplete Bug description: I cannot make a MacBookPro 11,1 suspend. When putting the lid down, acpi_listen prints: button/lid LID close button/lid LID open ... so the lid is signalling correctly. Upon opening, the screensaver prompt is present, and typing in the password brings me back to the desktop. Nothing is found in dmesg. When choosing "suspend" from the top-right power menu, the screen goes black and shortly lights up again, showing the screensaver login prompt. Typing in the password brings me back to the desktop as if nothing had happened. To remark that the power menu in the System Settings shows sometimes "Suspend" as greyed out.
