In the old BIOS, [ 0.000000] Reserving Intel graphics memory at 0x00000000c1000000-0x00000000c2ffffff which was not marked up as reserved inside the e820. It seems to be e820_reserve_resources_late() is causing the conflict, but our earlier intel_graphics_stolen() should ideally have fixed up the e820 map.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
