dmesg boot log including error

This happened after resuming from S4 hibernate. Afterwards the system was
unstable (worked for a couple minutes then panicked with blinking keyboard
LEDs).

Attaching logs as per syslog instructions.

Kernel: 4.0.0-rc7+ (freedesktop git 631c2f8cb).

I also tried 4.0.0+ (freedesktop git 92bb36c80) but it wouldn't even boot on my
machine (blank screen).

3.19.0+ (freedesktop git 89271faca1) works fine including S4.

Hardware: MSI-7817 Haswell chipset, i5-4570 CPU. Ubuntu 14.04 with custom
kernel.

[    0.000000] Linux version 4.0.0-rc7+ (root at linuxkiste) (gcc version 4.8.2
(Ubuntu 4.8.2-19ubuntu1) ) #7 SMP Sat Apr 11 19:43:31 CEST 2015
