Eurocom M5 Pro system crash

[Dow Hurst]

Ubuntu 14.04.3 LTS

Kernel panics and system freezes pretty regularly. Under this kernel/OS combination the log below indicates a more specific message than on Linux Mint 3.16 or 3.19 kernels. After the kern.log message below, I've added the output of dmidecode from the laptop. This is a brand new Eurocom M5 Pro laptop received on Oct 9, 2015.

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same problem on the same laptop.

The system restarts regularly few times a day for no apparent reason (can't provide steps to reproduce..).

I set up Kernel Crash Dump Mechanism but then, even after very long time (~30 mins), the system wouldn't restart.
