Pascal, this bug is closed, but also about very different hardware to an
EeePC 1011PX. You should open a new bug.

Title:
  Xorg crashes on second and next unbind operations of Arc GPU

Bug description:
  Hello folks,

  Experimenting with new Lenovo Yoga i7 with Intel Arc on board and
  found that even if it's possible to disable the GPU to save power,
  Xorg session crashes the session after the second attempt (the first
  after reboot works just fine).

  This works like that - after poweroff/poweron of the system I execute the next commands:
  1. First attempt:
     * DRI_PRIME=1 glxinfo | grep 'OpenGL renderer'  # Shows: "OpenGL renderer string: Mesa Intel(R) Arc(tm) A370M Graphics (DG2)"
     * echo -n "0000:04:00.0" | sudo tee /sys/bus/pci/drivers/i915/unbind  # Works great
     * DRI_PRIME=1 glxinfo | grep 'OpenGL renderer'  # Shows: "OpenGL renderer string: Mesa Intel(R) Graphics (ADL GT2)", it's embedded graphics
     * echo -n "0000:04:00.0" | sudo tee /sys/bus/pci/drivers/i915/bind
     * DRI_PRIME=1 glxinfo | grep 'OpenGL renderer'  # Shows: "OpenGL renderer string: Mesa Intel(R) Arc(tm) A370M Graphics (DG2)"
  2. Second attempt:
     * echo -n "0000:04:00.0" | sudo tee /sys/bus/pci/drivers/i915/unbind  # Here the Xorg crashes, but I can login again
     * DRI_PRIME=1 glxinfo | grep 'OpenGL renderer'  # Shows: "OpenGL renderer string: Mesa Intel(R) Graphics (ADL GT2)", it's embedded graphics
     * echo -n "0000:04:00.0" | sudo tee /sys/bus/pci/drivers/i915/bind
     * DRI_PRIME=1 glxinfo | grep 'OpenGL renderer'  # Shows: "OpenGL renderer string: Mesa Intel(R) Arc(tm) A370M Graphics (DG2)"
  3. This and the next attempts are just the same as second one

  I collected the info and can reproduce this state after each reboot,
  so hopefully it will help you to find what's going wrong during second
  and next unbind operations. I can always help with additional
  information if you will need some.

  Thank you
