I recently installed Ubermix 3.0 on my Acer B115 and it quickly started suffering from complete freezes where nothing (including mouse cursor) would do anything, forcing a restart of the computer using the power button. The freezes would occur between 5 minutes and an hour of booting up the machine - generally closer to 5 minutes.

After some research and failed attempts to fix the problem by installing a new kernel, I came across the workaround that works. Turns out the problem has affected many people and is well documented, but there is a workaround - not a fix, as it causes the machine to be much less power efficient.

The issue is that many Intel Bay Trail machines with kernels newer than Linxu 3.16 have been suffering these system freezes. I see Urku flagged this in comments under the Ubermix 3.0 arrival blog with this link:

The workaround is to alter the grub.cfg by adding "intel_idle.max_cstate=1". I found the most useful guide to doing this (although pressing "SHIFT" to acces the POST didn't work - I needed to use "ESCAPE") was this:

With the workaround, it appears my machine is now working happily, but thought I better share to save others the big headaches I've been suffering trying to fix the issue.
