Bug Description
I realise that there are a number of bugs referencing an the "underrun on pipe X" issues with the intel driver. My issue doesn't appear to be addressed by any of them that I looked at however.
My issue is that early in the Xorg startup, I begin to get the underruns, and Xorg doesn't start. The attached log file shows what I mean. I have left it for a long time and had nothing more to show but a larger log file.
The system is a Intel Mac Mini Core Duo connected to a Toshiba Regza 42LX196. I have had no issues connecting other computers, with NVidia and ATI video cards, to the same TV. I am running Mythbuntu 8.10 (intrepid) fully patched, and I enabled the backports repo's just to see if there were any updates that helped.
The only other oddity I have noticed is that get-edid tells me "Something special has happened" though I don't suspect it's the display as my other computers seem to work fine with their drivers. I will attach the get-edid output as well.
Thanks!
