Title:
  Cannot boot:  kernel oops when i915 uses kms

Status in “linux” package in Ubuntu:
  Fix Committed

Bug description:
  Release is Ubuntu 11.04 beta 1

  I have a Dell E6500 latitude laptop with two monitors connected via
  Display Port.  When KMS is enabled, plymouthd aborts during init.  The
  segfault appears to be in the i915 kernel drm module and there is a
  printk regarding display port.  If I boot with nomodeset, then X will
  start but then xrandr does not work and I can only use one monitor.

  I have tried both the ubuntu 11.04 beta1  64-bit desktop and lubuntu
  110.4 32-bit beta1 LIVE discs with the same results.

  I am currently running ubuntu 10.10 64-bit on the same machine with no
  problems.  I would like to upgrade but this is obviously not possible
  as long as this bug persists.
