PROBLEM: random hard freezes under X on Intel BayTrail-based machines unless intel_idle.max_cstate=1 is set

From: Thomas Moestl <hidden>
Date: 2016-01-09 22:32:25

[1.] One line summary of the problem:
Intel BayTrail-based machine experience hard freezes, as reported at e.g. https://bugzilla.kernel.org/show_bug.cgi?id=109051

[2.] Full description of the problem/report:
In my case, the machine in question is an ASUS R752MA laptop, but many other people
seem to be experiencing similar problems on a variety of BayTrail-based hardware
(see below).

System freezes hard when working under X, sometimes after minutes, sometimes after
hours. Usually, but not always, graphics-intensive applications like viewing videos
will trigger the hangs after a while, but they can also (much more rarely) occur when
e.g. only an xterm is opened and being worked in under.
The MagicSysReq keys are not functional any more once the hang has occurred, there
is no information in the logs, and no crash dump can be obtained by using the soft or
nmi watchdogs, panic_on_oops etc.

Some research has led me to https://bugzilla.kernel.org/show_bug.cgi?id=109051 ,
and I believe that it describes the exact problem I am experiencing. As you
can see from that bug report, the intel-drm team believes that the graphics
drivers are not to blame, and merely trigger the issue.
https://bugs.freedesktop.org/show_bug.cgi?id=88012 gives an overview of the
history of the drm-intel team's efforts regarding this issue.

As described in that report, adding intel_idle.max_cstate=1 seems to eliminate
the problem completely, and I am experiencing no freezes or other kernel problems
at all with it.
