            Bug ID: 89848
           Summary: i915: framebuffer corruption when switching tty or
                    quitting x-server with kernel >=4.0
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org

Using any of the 4.0 kernels I get framebuffer corruption when switching tty or
quitting X.
my dmesg output gives:

[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO
underrun

Some people running 3.19 are getting corruption when running multiple displays,
with 'pipe B FIFO underrun'.
