yes, I used 2021.04-rcXX( master, self-compiled)=E2=80=A6 the strange =
thing on Rock960-board was that it needed some reboots=20
until nvme was scanned correctly in u-boot-prompt.

I presume an electrical issue since it was once(only once) detected by =
adding nvme_load=3D=E2=80=9EYES=E2=80=9C& nvd_load=3D=E2=80=9EYES=E2=80=9C=
 in rc.conf.=20
The u-boot patch related to nvme on that board also was based on a =
voltage-change .
=E2=80=A6 I`ll post some debug-output the next hours=E2=80=A6 (`guess =
pcie has mem alloc issue from dmesg)=E2=80=A6

Anyone successfully booting from nvme on any aarch64-board ??

K.
