Comment 7 for bug 1812758

I had some luck with Dell after I told them to give me a different machine. Finally got in touch with someone with Dell support that checked their knowledge base.

There is an option in the Dell BIOS that has to do with "Intel VMD Technology". The solution that Dell provided was to disable the VMD feature (e.g.mark it as disabled) and in the PCIE Devices list: uncheck all devices and reboot.

After doing that, 16.04 and 18.04 now seem to boot without any kernel flags (as long as the nouveau driver supports the card). I'm still doing testing to make sure that this is a work around where the machine will see all devices instead of just 1 core.

Will report back with the results.
