[Bug 492392] Re: [lucid, intel] After suspend, flickering screen and then blank screen.

[Stefan Bader]

** Description changed:

+ This bugfix is included in the DRM update to 2.6.33.5 upstream stable
+ (see Bug #588832).

+ ---

  This is a regression introduced by the .32 kernel its also present on a
  stock .32 kernel.After resuming from suspend I'm experiencing an issue
  where my screen flickers then eventually goes blank, normally black
  although its been white or blue on occasions.At first I though this was
  a KMS issue but after disabling KMS its still present.I'm not sure how
  to debug this further so any advice would be appreciated.
  
  Thanks
