Mid2014 Macbook Pro Retina here. Same issue, but the effect is even worse. It literally takes half a minute until suspend happens (you can see it by using pm-suspend instead of closing the lid, because you can watch keyboard backlight then). Problem is: Suspend sometimes fails and then the Mac wakes up again, even if lid is closed. And it does not make any efforts to go to sleep again.
This is CRITICAL, because if you close your laptop, put it in your back, then you will find out hours later that it was running all the time, with high risk to overheat damage. Of course nowadays the CPU will switch off before it burns, but it still was much too hot and may do damage to other parts of the computer like batteries and SSD. I run 14.10 since October, and suspend worked fine for the first weeks, but for a few days now it wakes up very often when lid is closed. -- 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/1323645 Title: [MacBookPro11,1] Suspend delayed because of some timeout issue Status in “linux” package in Ubuntu: Confirmed Bug description: As requested by apw, here is the bug report for suspend problem on Macbook retina.
