Comment 7 for bug 1518566

I am experiencing this bug as well, on the same hardware. I have tested the mainline builds, and can confirm that the bug
exists with linux-image-4.4.0-040400rc7-generic_4.4.0-040400rc7.201512272230_amd64 as well.

After some searching, it appears that this bug is known in upstream: https://bugzilla.kernel.org/show_bug.cgi?id=109051

As such, it probably occurs on most machines with Intel BayTrail processors, and is so far unresolved in upstream,
to my knowledge.

As the bug report mentions, there is a workaround, namely to add "intel_idle.max_cstate=1" to the boot options
(using grub, add this to the GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub, then run update-grub). This likely
comes at the cost of some increase in power consumption, but so far it seems to work for me. If I get any more
hangs even with this option, I will leave another comment.
