Ubuntu froze again after BIOS upgrade, so this is reproducible.

Spyros Theodoritsis, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results.

Thank you for your understanding.

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.

X751MA is also Bay Trail based so cause could be same as here:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1531865

I built Ubuntu-4.2.0-23.28 with "drm/i915: Agressive downclocking on Baytrail" reversed and it can be found from here:

http://www.helsinki.fi/~jmoheikk/baytrail/

If you could test whether it works or not.

I did the workaround yesterday and up to the moment I have zero freezes. Thanks Thomas for the tip, hope this will be fixed upstream.
