I used to have the same issue. Last week I updated "managed=true" in /etc/NetworkManager/NetworkManager.conf (to fix a seemingly unrelated wifi connection issue), and the suspend/resume problem disappears. If you also use the Network Manager applet (which is the default on Ubuntu), I suggest you try this fix.
(I don't know why this fix works. But it seems to do the job.) -- 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/1306621 Title: [LENOVO ThinkPad T440s] suspend/resume failure Status in “linux” package in Ubuntu: Incomplete Bug description: 1.
