You are right to clarify. My concern is that this problem appears randomly for each kernel version, even on minor updates on 14.04 kernel (has I said at the beginning), so I wanted to give a global vision of the problem. The link to the SRU procedure is very interesting, but : - I do not have

I just downloaded and tried the daily-live image. It seems there is no problem with resuming from suspend, but after a resume I can not suspend again before approximately one minute. It was difficult to test this, the current image has bugs, at least for my computer : - /home/ubuntu/.config is

Yvan Masson, just to clarify, the scope of this report is only about suspending at all (not about an issue performing subsequent suspends within a minute after a resume from suspend, or any of the other issues mentioned). All of the other issues would need to be filed as separate reports, one per

Yvan Masson, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream

Thanks for the fast answer. Pleas apologize, but I do not understand where I should get the upstream kernel : from the Linus git repository (http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git) or from the Ubuntu kernel PPA (http://kernel.ubuntu.com/~kernel-ppa/mainline/) ? -- You

Thanks very much for this complete and interesting answer. I can't easily test this because I first need to upgrade OS X (fortunately it is still on disk) : the EFI update needs a recent version… I will update the bug report when done. Yvan -- You received this bug notification because you are
