Please try to disable the VMD option in BIOS and try again.
Thanks. But I can't find any VMD or Volume Management settings in Dell XPS 8940 BIOS. Can I assume it already disabled?
Hi @TerrenceXu, is there other ways to disable VMD?
Can I disable VMD by write the register "Capability B - offset E8h" of Host Bridge and DRAM Controller (D0:F0)? But I don't know the base address of that controller, can you give some tips on this? And I don't know what does D0:F0 means?
@z7z8th , I am not sure whether your issue is related to VMD, just for a try.
BTW, can you provide your full "dmesg" log and "cat /proc/cmdline" log? and what is your reproduce steps.
@TerrenceXu Attached dmesg-1.log
