Title:
  Kernel Oops - unable to handle kernel NULL pointer dereference at
  0000000000000010; EIP is at fb_release+0x26/0x60

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  My laptop has a kernel problem with the Ubuntu 15.04 live disk.

  The Kernel reports constantly about a NULL pointer reference.

  Sometimes the X-server starts without the Unity interface and the UI freezes constantly for a few seconds.
  It often ends with a complete freeze of the computer.

  Other times the computer freezes before the desktop was loaded.

  I think it could be the radeon driver for my ATI Mobility Radeon HD
  5650.
