Running FreeBSD on M.2 SSD

[Mario Olofo]

Yes, tried 4k quirk but not on install because don't know how to, I did a
clean install then patch and rebuild the kernel, but
the volume was already configured for 512bytes, I think I would need to
create manually the volume, but don't remember how to anymore xD
But I'll search some tutorials and try. From what I saw, the patch
suggested on bugzilla got merged into the stable branch, so the quirk will
be
detected to use 4k in the installer in a near future.
