i915 graphics errors detected
When I use Knoppix 6.4.4 on my dell notebook with intel graphics, I got
this in the 'dmesg' output. Anyone see the same thing on their i915
intel graphics ? I found many similar posts on the net, but none has
provided with a fix.
Code:

I've got an Inspiron 1545; dmesg | grep 915 gives me:
[ 21.812915] atkbd serio0: Use 'setkeycodes e00d <keycode>' to make it known.

dmesg | grep -i error gives, among other things that are probably not pertinent:
[ 48.588813] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero.
[ 48.983136] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero.
[ 48.990094] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero.
[ 48.990099] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero.
The backlight problem is a known problem, which doesn't affect me using the laptop
as a desktop.
