Bryce & others,

It seems this issue is relevant to many (if not all?) Intel chipset users. I have access to three systems with integrated graphics - a 900GMA desktop, 865G desktop and 855GM laptop - and none of these systems setup write-combining MTRR ranges properly.

Although this causes issues mostly with video playback, it will only exacerbate complaints of slowness for Intel users in the Jaunty release. I suggest this bug is treated as a high priority and squished in a SRU as soon as possible.

Do you need any further logs or debug information to help?
