[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

Can you also see if this issue exists on Raring?

[Joseph Salisbury (jsalisbury)]

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

[Jeff Marcom (jeffmarcom)]

Sure, I'm testing 12.10 right now, and will certaintly try raring and 12.04.1

[Jeff Marcom (jeffmarcom)]

quantal works

@Jeff, hi Jeff, could you please help to verify if 12.04.3 works ? thanks very much.

[Jeff Marcom (jeffmarcom)]

This is still an issue with 12.04.3 unfortunately :/

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
