[Intel-gfx] X crashes when terminating application

[Maurice van der Pot]

Hi,

I've set up a pretty minimal system using Gentoo to build the packages I
need on the target. I'm having some issues with X though. X seems to
start up fine (no errors in the log), although I can't be sure for the
moment because I think the output is sent to an unconnected LVDS
connector.

Now when I run any X program (xterm, xclock, xrandr) and it terminates
(either by itself or through me ctrl-C-ing), X crashes with the
following output:

  Dropping master
  error setting MTRR (base = 0xd0000000, size = 0x10000000, type = 1) Invalid argument (22)
  (EE) intel(0): Failed to initialize kernel memory manager

  Backtrace:

  Fatal server error:
  Caught signal 11.  Server aborting

I checked and found that errno is set to "Permission denied" when "Failed to
initialize kernel memory manager" is printed.

This is what is logged to the X log when I terminate the application:
  (II) UnloadModule: "mouse"
  (II) UnloadModule: "kbd"
  (WW) Open ACPI failed (/var/run/acpid.socket) (No such file or directory)
  (II) No APM support in BIOS or kernel
  (II) intel(0): Kernel reported 238592 total, 1 used
  (II) intel(0): I830CheckAvailableMemory: 954364 kB available
  (II) intel(0): [DRI2] Setup complete
  (**) intel(0): Framebuffer compression enabled
  (**) intel(0): Tiling enabled
  (**) intel(0): SwapBuffers wait enabled
  (EE) intel(0): Failed to initialize kernel memory manager
  (==) intel(0): VideoRam: 262144 KB
  (II) intel(0): Attempting memory allocation with tiled buffers.

Followed by the same stacktrace.

This is with linux 2.6.30.4 and xf86-video-intel 2.8.0.

Any idea what's going on here? What could make the ioctl for GEM_INIT
return permission denied and why would this initialisation be done when
an application is terminated?

Thanks,
Maurice.
