As mentioned, I tried to bisect a couple of months ago without much luck, either because of compiling problems or the Heisenbug behavior.

In the meantime, I removed the no_console_suspend argument from the kernel command line (which I originally added while doing the bisecting work) and now the suspend act seems to be much more stable; I think I haven't seen the failure again since I switched to 3.18rc7 a couple of weeks ago (and now at 3.18.1).

That might be pure coincidence, or maybe something related has changed (I also upgraded Debian in the meantime), I cannot tell the exact reason right now. I could try to add the no_console_suspend switch after Xmas to check whether the problem returns.
