[Launchpad Bug Tracker <560056@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

I downloaded the beta 2 ISO from the servers and made a LiveCD for fresh
install of 10.04. The boot process is carried out until near the end,
the purple plymouth screen goes away and then all I get is flickering
screen with lines running across it. I did a few things like "nomodeset"
and "pci=nomsi" but nothing does. The later one sends the monitor into
power saving mode and the only way out is a hard reboot.

I tried to drop to the terminal when the screen starts to flicker and
ran

#dmesg | grep drm

and there are error messages related to my graphics card. Seems like for
some reason the GPU is being reset every few seconds. See the screen
shot attached for the exact error messages.

I'm trying to boot Lucid on system which includes:

Interl i5
ATI Radeon HD4730
4GB RAM
Dual monitor
