System doesn't resume from suspend (Debian, Lenovo ThinkPad E555)
I have a Lenovo E555 running Debian stable (Jessie, 8.7, kernel 3.16.0-4-amd64). This is a brand-new setup, so there is no history of suspend working in the past.
The system will go into suspend fine - screen off, and the power light doing a slow blink (this is the expected behavior). When I attempt to resume, the power light goes solid, but the screen never turns back on.
As part of my troubleshooting, I have:
1. Temporarily blacklisted the kernel modules for my Wi-Fi card that had been leaving call traces in my log files
2. Have been testing suspend at runlevel 2 so a lot of unnecessary services are disabled (manually run "systemctl suspend" from the command line).
This gets me much cleaner log files, but does not solve the problem.
Does anybody have any ideas where to go next in troubleshooting this?
Here is my /var/log/messages from an attempted suspend and resume:
