[Bug 1380382] Re: ASUS K53S fails to suspend

I started having problems with suspend and resume after upgrading to
kernel 3.13.0-37. Resume takes a long time, suspend sometimes takes me
to the log in screen and I have no networking after resuming (I need to
restart Network Manager). I am running Ubuntu 14.04 (64 bit) on a DELL
XPS 13 (full HD, Intel GPU) notebook. Everything works fine with kernel
3.13.0-36.
