I have Windows Vista on my ASUS F5GL. After trying to boot Ubuntu (from DVD or USB either) these error messages occur:
[DRM] GPU lockup - switching to software fbcon  failed to idle channel 0xcccc0001 [PFIF0] [0000:02:00.0] channel 3 unload timeout etc.
The installation won't start and these messages run in a cycle. Please, could you help me to solve this?
