Issue/Question: High CPU Usage

Description: Clean install of LinuxMint on ASUS ChromeBox (upgraded with 120GB SSD & 8GB or RAM) . Everything appears to be working but system monitor reports one CPU always around 68% load and the other CPU around 2% load. I have already updated to Kernel 3.14.1 and installed the Intel Linux Drivers.  When running the mpstat command, it shows that %sys is running around 64.04 on 1st cpu  and 4.2 on 2nd CPU. The top command doesn't really echo these findings ... (or maybe I am not reading it right.) Regardless, there doesn't seem to be an easily identifiable culprit as to what the cause is.

On a normal-full installation of Ubuntu using the Chrubuntu script, I was averaging around 20% CPU load in idle  (no apps running). This was until it updated to 14.04 yesterday and the loads jumped again. This is what compelled me to try a clean install.

I am almost positive that there is some mod, driver install, custom setting that was done on the Chrubuntu script that allowed for better compatibility with the hardware ... or something to that effect. 

Any ideas, thoughts, or suggestions?

I have taken some additional steps and wanted to provide further notes for the purpose of this conversation ...

I did a complete restore of Chrome OS and started the process all over using the Chrubuntu script which now installs 14.04 by default. After all is said and done, it does work but again is showing much greater CPU usage of one of the cores. It also seems a bit sluggish at times when -- just yesterday, when using the Chrubuntu 12.x install, it was very snappy. 

Question: Has anyone else noticed the higher CPU loads in 14.04 ... is there some hardware compatibility, driver, or setting that was installed with the old script that is no longer installed? Just our of ideas on this ...

Question: Is it possible to "unset" the bios flags -- in case you wanted to go back to booting to default instead of legacy? Is it a matter of just re-running the script? Many thanks in advance -- apologies if this was already answered, I did look before asking.

Even with the flags set you can still boot ChromeOS by using CTRL D.

Thanks John for the hard work and time invested on this; Slainte. 

I recently purchased the ASUS Chromebox and have been working through the various methods of running Linux; successfully installed Crouton and Chrubuntu. I have been researching the options to boot straight to legacy mode but information on the Chromebox is a bit limited at the moment. 

I throw this out for those who are working on similar projects,

1) It is my understanding that the newest mainline Kernels have the necessary modules/drivers included to work for Haswell based Chromebook/Box? Is this correct? I did upgrade my kernel to 3.14.r7 on the legacy Ubuntu and all seems to work well.

2)  If anyone knows about how to unlock (if needed) the bios on the Asus Chromebox?

3) While I have followed all of the instructions I can find, I can't seem to boot to USB. Even when I boot to Legacy Mode and hit ESC, its as though it does not recognize that I am hitting that key. I would like to install LinuxMint from a USB drive but I can't get to it. 

Many thanks in advance for any and all advice or suggestions this community can provide.

Gaming News: For those looking forward to getting one of the new consoles coming out, the PS4 will be released on November 15th; just in time for Holiday Shopping Madness. As for the Xbox One, the release date is still unknown. 

The good news for Microsoft Fans, if any, is that Microsoft has pretty much made an about face and reversed many of their initial plans and decisions with respects to the XBox One requirements (online access 24/7, game sharing restrictions, need to have the Kinect Camera always on, etc.) These moves have helped counter the very vocal backlash following the product unveiling a few months back.

That being said, with significantly more power and a more affordable price ($100 difference) the PS4 remains the pre-game (pun) favorite. As always, only time will tell.

Compiled a new guide for the new Asus Chromebox based on all of the information I collected thanks to communities like this and the efforts of individuals like John Lewis. Just trying to help others ..  please feel free to provide feedback (always a dangerous thing to say.)

Question: (Apologies in advanced if this has been hashed out -- I have Google Searched)  Are there instructions to upgrade the Kernel on Chrome so that Crouton is using the newer 3.13 or 3.14 Kernels? And ... is it possible to use the generic 3.14 Kernels (as I have read that the ChromeOS modules were merged at some point? I have the new ASUS Chromebox and would like to take advantage of the better drivers for new CPU.
