Simon, given the issue happens in both Windows and Ubuntu, have you had
a chance to discuss this in more depth with ASUS so they may address it
more properly at the BIOS level as applicable?

The above reports are collected while running above the vendor's custom
throttle throttle threshold. Right now: waiting for the battery to
discharge.

That's exactly what I tried on my second RMA Attempt. I was trying to
use Windows 8.1 and had intermittent shutdowns.
It was all like:
-- I downloaded all the official drivers and power management software from
your website. It hangs.
-- We do all the testing on Windows 7. This model does not
Here's a short video I recorded for the ASUS Support service. It gives a
good illustration of what happens on Windows 8.1. This is also exactly
what I get with the latest Ubuntu LiveCD.
In the video, I say in Russian: Now I'm plugging in the AC... Rebooting
the device... And it works perfectly...
Right now, I'm downloading http://cdimage.ubuntu.com/daily-live/current
/vivid-desktop-amd64.iso and soon will be posting the apport-collect
reports: one during operation above the vendor-induced custom throttle
threshold and another after it kicks in.
On Friday, I contacted ASUS for a third time

SNA acceleration
Simon, your best bet to bypass ASUS tier 1 altogether by requesting an
escalation.
I always contain the discussion with vendors to the factory operating
system that came pre-installed when purchased, as they tend to use any
deviation from this (even just using a scratch install of the same
UPDATE: The system is fully stable only if I both use a modded
overclocker edition Sandy Bridge CPU microcode (Rev. 28) embedded into
the BIOS and set the kernel boot arg i915.enable_rc6=5.
The modded microcode allegedly allows the CPU to consume less power when
operating at higher frequencies,
I'll be able to do it some time before Monday. Sorry for not doing so
right away.
Meanwhile, bad news. This behavior is by design. Running custom
microcode and setting rc6 to 5 does not fix the issue, it's just an ugly
workaround. One thing I've been missing all these weeks which I
discovered
Simon, great! Are you able to execute the apport-collect in a live
environment via http://cdimage.ubuntu.com/daily-live/current/ ?

After enabling the hidden BIOS options for Native ASPM and Native PCIE
Runtime PM and disabling the C-states, I got rid of the issue (a hard
CMOS reset was necessary for the BIOS modification to fully kick in)
The C-states continued to work in Ubuntu, though, due to the nature of

Simon, you may have more success using a Unity live environment, versus
KDE.
As well, if it's a BIOS problem, it would be best to start with the
latest, unmodified BIOS from the vendor (despite it appearing to be
older/buggy), as they tend not to indulge BIOS modifications.

Okay, I'll download a regular Ubuntu 14.04.2 LiveCD and use it to
prepare the diagnostics info. I won't be using a modified BIOS at that
time.
I'm currently switching between the latest official and my custom BIOS.
The latest BIOS 214 is known to have caused similar behavior in WIndows
8.1, and
