I'm suffering an issue my Thinkpad X1 Carbon can't resume after suspend recently. I tried many ways including latest vanilla kernel, latest stable 3.13 and 3.11 kernel but it still happens. I found it will not happen when I turn off WIFI device or USB 3.0 in BIOS. So I suspect something need fix in either wifi driver or USB side. Since Windows 7 works good so I suppose no hardware issue. Anyone has some ideas to fix it or debug it?
