Title:
  GUI crashed after installed proposed package libegl-mesa0

Status in linux-oem-6.1 package in Ubuntu:
  Invalid
Status in mesa package in Ubuntu:
  Invalid
Status in linux-oem-6.1 source package in Jammy:
  Won't Fix
Status in mesa source package in Jammy:
  Fix Committed

Bug description:
  [Impact]

  OEM-6.1 kernel is missing support for minimum page size of 64k on DG2
  (gfx12.5). Mesa 23.2 started using that, so it broke initializing the
  gpu on boot, causing a blank screen with no GDM running (with wayland,
  and fallback to X failed too).

  [Fix]

  Revert the commit that allows using 64k page size, since that's what
  the current version in jammy-updates is using. OEM-6.1 kernel is going
  away, no need to patch that anymore. No other kernel is affected, >6.2
  works fine and thus this revert is not necessary in mantic or noble.

  [Test case]

  Install the update, boot up a machine with DG2 (iGPU or dGPU, doesn't
  matter). The login screen should appear.

  [Where things could go wrong]
  Hard to see how this could regress anything, as it just restores the limits 
for intel gfx12.5 as they were in the current mesa version in jammy.

  ---
