2016-01-02 23:24:37 penalvch description 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 Unity. 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. The BIOS was updated to the latest version available from ASUS: I have tried the latest mainline kernel build from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D , linux-image-4.4.0-040400rc7-generic_4.4.0-040400rc7.201512272230_amd64.deb (4.4-rc7), and the hangs still occur under the same circumstances. 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. In particular, the workaround mentioned in there. adding the intel_idle.max_cstate=1 kernel option, seems to work for me (and my machine is based on the Intel BayTrail, as mentioned in that report). (I am writing this report with this option with this enabled now, so don't be surprised to see it in the kernel command line).
