If anyone still has the legacy bios install, I'd be interested to know if passing processor.nocst in the kernel boot options has any affect on the problem. Thanks!

However, on restart the machine will not boot. It hangs at: https://www.dropbox.com/s/behviox991o01o1/2014-02-23%2016.15.15.jpg Per apw in #ubuntu-kernel a test to add nr_cpus=1 does work to boot the machine. Note that wifi does not work at this point, but it does work in the live usb boot. For more information I did hit this with both the 3.13.0-8 and 3.13.0-11 kernels as I tried to update. --- Original notes --- I'm attempting to install and run 14.04 trusty on a macbook air in a dual boot configuration. I have a Mac 64bit iso bootable usb device that I used to install on top of refind. The very first time I installed and setup it worked. I was in Ubuntu. I installed updates and some basic packages and when I rebooted it would no longer boot. I had gotten an updated kernel so I attempted to boot to the older -08 kernel with no luck. I then attempted to reinstall. I figured I could avoid updates for the moment. I used the USB stick to do an install using the "Remove 14.04 and install" option. When it was done, it would not boot just as before. I attempted to use the usb stick to rebuild grub using http://howtoubuntu.org/how-to-repair-restore-reinstall-grub-2-with-a -ubuntu-live-cd with no luck. I've tried setting boot params in grub of nomodeset noapic. When I turn off the quiet mode I get the following screenshot where it hangs very early in the boot process around "Booting SMP configuration".
