I also wanted to install Linux on my EZbook 2 (with the Z8300 CPU) and here are my findings:
Sound works on almost every distro out of the box.
Touchpad works on almost every distro if you disable hid_multitouch with
sudo modprobe -r hid_multitouch
Wifi ONLY works with Ubuntu Budgie if you rename brcmfmac43430a0-sdio.jumper-ezpad-mini3.txt to brcmfmac43430a0-sdio.txt in /lib/firmware/brcm/ and reload brcmfmac.
Distros I have tried are Ubuntu, Kubuntu, Ubuntu Budgie, Manjaro KDE.
Manjaro KDE runs much smoother than Budgie and I would prefere the KDE desktop over the others.
Finally, I don’t think I will switch to Linux yet, but will sure try to run Linux, when future updates are released.
