So what about just disabling VMD given how bloody pointless it is?
Hasn't anyone learned from the AHCI remapping debacle?
I'm really pissed at all this pointless crap intel comes up with just
to make life hard for absolutely no gain. Is it so hard to just leave
a NVMe device as a standard NVMe device instead of f*^&ing everything
up in the chipset to make OS support a pain and I/O slower than by
doing nothing?
