[Bug 328918] Re: [i945] underrun on pipe A! prevents Xorg from starting.

[Bryce Harrington]

** Description changed:

  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!
