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:/
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:/
Can this be verified by some other method e.g. by disabling/reverting 1434581 in a "normal" non-mainline kernel?

I'm unable to run 'apport-collect 1561902', as it says "Package linux-lts-utopic not installed and no hook available, ignoring". Any help?
