Yes, after a fresh install of the stable version I noticed that the immediate start after suspend problem came back. I found that my previous installation included a script to disable WOL in the E1000 adapter (created by me). I installed the 4.1.6 beta and this problem went away, and checked at OS level that WOL is not disabled. I asume, then, that the kernel in the beta includes a patch for the E1000 to fix this.
