Comment 25 for bug 984387

A workaround to be able to install Precise on these systems:
- Boot with a 12.04 Live CD or USB.
- Press a key to acces the options, select your language.
- Press f6 to edit the commandline (advanced options), then press esc to dismiss the popup.
- On the kernel command line, after the --, add ite_cir.blacklist=yes
- Press enter

This will allow you to boot into the Live environment and try out or install 12.04.

On first boot, you'll be affected by this problem again, so:
- When booting, right after your PC's POST routine finishes, press the right SHIFT key. Keep it pressed until the GRUB menu appears.
- Press 'e' to edit parameters for the boot entry.
- Move down to the "linux" line (next to last), then move to the end of that line.
- again, type ite_cir.blacklist=yes at the end of this line
- Press ctrl-x.

This should have you booted into your new system. From here you can do the workaround from comment #6 to make the blacklisting permanent.
