Public bug reported:
Problem,
I'm currently unable to install 12.04.2 via PXE or live cd image.
When trying to install via PXE the machine will hang with the following
kernel messages showing:
[0.004205] [Firmware Info]: CPU: Re-enabling disabled Toplogy Extensions Support
[0.004254] CPU: Physical Processor ID: -
[0.004293] CPU: Processor Core ID: 0
[0.004322] mce: CPU supports 7 MCE banks
p0.006443] ACPI: Core revision 20120320
Whey trying to install via Live CD or Live USB I receive the following message:
"If you're seeing this the installation has failed", from this point I can
select to boot into single user mode, or an automated install.
Selecting either causes the machine to hang with a cursor in the top left
corner.
Reproducable?: Yes
I've reset all BIOS settings to the default values.
In 12.04.1 the system will attempt to boot from the key/CD after
selecting "Install Ubuntu" and proceed (trackpad is disabled and Ubuntu
Desktop never loads"
When trying to boot raring live image, the machine simply reboots never
displaying a Grub Menu option.
I have confirmed that the live images I was using are working with other
machines without issue.
