Sometimes system does not wake up from sleep.

[Rodgrod]

Hey there,

I'm running Gentoo ~amd64 with kernel 4.7.0-gentoo for a couple of days now on my new machine and so far everything seemed to work just fine. Yesterday, all of a sudden, the system would not resume from sleep. The fans were turning on, by the system did not respond to anything. The screen stayed black, it did not react to keyboard input (hitting numlock had no effect) and if I inserted a USB drive, there did not seem to be any access to it (LED not flashing). What's really problematic, is that this behaviour happens in about 1 out of 10 cases. I tried to reproduce that problem, but I did not find out when the problem occurs.

Here is a successful sleep-wakeup-cycle from pm-suspend.log:

yes I've had a similar issue ..but network reconnection related only on wake-up.. reverted to 4.6.6 to test if the issue is kernel related or some otjher software .. still wating to see a network freeze-up... perhaps something is not fully recovering with kernel 4.7.0 .. time to search kernel.org for bugs

thus .. I checked your paste.bin .. looks like you have errors in libglib .. suggest a recompile perhaps .. have you recently changed/upgraded compilers?

gcc ujpgrades at the moment are not necessarily ABI compatible especially for c++ based programs .. I tend to rebuild @system when changing gcc versions just in case .. YMMV
