Bug Description

[Lenovo L420]: System hangs at random spots during 12.04.2 install

Problem:

This machine was previously blocked for certification due to bug #990110. I downloaded the requested BIOS update from lenovo's site version: 1.20 and attempting an install via a live iso. While attempting the install the system would intermittently lose touchpad functionality and lock up. It will eventually stop responding to all keyboard and mouse activity and the progress indicator will halt implying the system has stopped. At this point you cannot switch to an alternate tty.

Reproducible: yes

It would also be helpful to know if it happens with 12.04.1 and/or Quantal
