I installed Ubuntu dual-booting alongside Windows XP. After completing the install and rebooting, the machine froze, with this error message:

GPU lockup- switching to software fbcon
Failed to idle channel 1, 2, 3
PGraph TLB flush idle timeout fail

The graphics on the screen then went random and pixelated.
