@kratkale Full disclosure I haven’t read your whole post, but I have Z2 xx G1i’s
Disable intel VMD and it should work.
VMD was supported in intel 12th-14th gen chips for sure in our fos linux kernel, but something changed on the core ultra x line. It does exist in the linux kernel, and we have VMD enabled in the linux kernel, but there’s some other piece missing that I hope to find one day.
But the quick fix is to disable VMD and the drive will be seen and all will be well.
