Hi,
at least for me the EzBook 3 Pro seems to have the same bug described here:
https://bugzilla.kernel.org/show_bug.cgi?id=109051
I used Arch Linux with Kernel 4.12.3 -4.12.5 and XFCE as Desktop.
I got freezes after 2 – 6 hours. Especially when using Chrome or Firefox. So I deleted Linux for now.
What Linux distros are you using and are they running stable?
Shame, this would have been nearly the perfect Linux notebook 🙁
