unable to boot after install on 2013 macbook air
Status in Release Notes for Ubuntu:
Status in linux package in Ubuntu:
Booting and installing from a live usb for trusty does work. However,
on restart the machine will not boot. It hangs at:
Per apw in #ubuntu-kernel a test to add nr_cpus=1 does work to boot
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
I attempted to use the usb stick to rebuild grub using
-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".
