Windows 10 is freezing in the exact same way. I guess something is
broken in this laptop and I'll keep using 3.13.x now and Windows 7 until
2019. If the laptop survives that far :) thanks for the help Stefan!

Title:
Total system freeze after 3.16.0-38.52
Status in linux-lts-utopic package in Ubuntu:
Invalid
Bug description:
This should have been reported already last year, but here it goes.
Problem:
My laptop is a ASUS N71JA and works perfectly in Windows. Everything was fine
with Xubuntu 14.04 through kernels 3.13 and 3.16 up to 3.16.0-38.52. Desktop
freezes, like totally dies with hard power reset being the only option, every
now and then from this kernel and onwards. This affects 3.19 and 4.2.0 kernels
released after this date as well. No Magic SysRq possible and I can't see
anything fancy in syslog or kern.log. Desktop can die anytime between
immediately after boot or after a few hours, but it happens completely randomly
and is hard to debug.
Workaround:
3.16.0-38.52 was released in May 2015
(https://bugs.launchpad.net/ubuntu/+source/linux-lts-utopic/+bug/1452882).
3.16.0-37.51 and 3.16.0-36.48 have NEVER frozen.
The only non-upstream change that was made to 3.16.0-38.52 was
"vesafb: Set mtrr:3 (write-combining) as default"
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1434581). This
is probably not implemented in the mainline kernel tree, right? I've
been using mainline 3.16.7-ckt24-trusty without any problems now for
over a month (http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.16.7-ckt24-trusty/) i.e. it seems like 1434581 is
causing the problem.
Can this be verified by some other method e.g. by disabling/reverting
1434581 in a "normal" non-mainline kernel?
Solution:
?
