After a number of attempts I only managed to repeat it once, and that was with plugging in mains immediately after (practically simultaneously) closing the lid; so possibly while suspend mode is being entered. The time it happened, the backlight had gone off, then it came on again briefly, then off. Then when I opened the lid it was dead.
But i couldn't make it happen again, so it may be *extremely* timing- sensitive and rare. Anyway I'll install the 3.14 kernel, but it's going to be hard to prove the negative given the positive is so chancy... But I suppose if it *does* happen, that tells us something and I could at least tag it kernel-bug-exists-upstream. -- 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/1299790 Title: [Apple Inc. MacBookAir4,1] suspend/resume failure [non-free: wl] Status in “linux” package in Ubuntu: Incomplete Bug description: I had shut the lid to suspend the system last night. *After that* I plugged in the mains lead. Today I unplugged the mains lead and *then* opened the lid, and tried to wake it, only to find it wouldn't do so. Had to force-reboot it. On logging into desktop, this bug report got triggered. It had been through some suspend/resume cycles already (not many; i only installed it on Friday), so the mains-plug behaviour is where I suspect the problem is.
