I tried to get more information by following https://wiki.ubuntu.com/DebuggingKernelSuspend
The resume failure happens regardless of which suspend method I use: shutting lid, click suspend in gui, pm-suspend Regarding booting into the latest mainline kernel: Should I really use the latest (v4.2-rc8-unstable) or the latest for my version of Ubuntu (v3.15-rc2-trusty)? I tried the "resume-trace" debugging procedure, but I'm not sure, it gave a usable result: grep -i -A 3 -B 3 "hash matches" dmesg.txt [ 1.308444] IMA: No TPM chip found, activating TPM-bypass!

What happens: - Fans and HD spin up - HD LED does not light up (it should blink if there is disk activity) - Screen stays black At the moment I can not say, after which kernel version this started to happen, I will try to find a version that works.
