[Bug 342122] Re: [drm:drm_release] *ERROR* reclaim_buffers_locked() deadlock

[Bryce Harrington]

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  This affects 8.10 Intrepid desktop live-CD boot - currently not able to
  install to the hard disk.
  
  Sony Vaio PCG-SRX51P/B notebook with Intel i815M video and 384MB RAM.
  
  When X starts the screen becomes totally black with no cursor.

  It is possible to switch to a console terminal although the usable area
  is a small section in the centre of the 1024x768 display.

  ----------
  
  Disabling DRI in /etc/X11/xorg.conf helps only slightly in that X tries
  to reconfigure the display and gets stuck in a loop of dialog choices
  (very small - 6px - text too) which results in it using the 'generic'
  profile again which tries to use DRI and therefore the screen is blank
  once more.
