The first question is, how large is the md_image and what other modules are
loaded?

Thanks for your quick response.

The images are 50-500MB uncompressed (provided by gzip compressed file).
Small ammount of elf modules, 5, each ~50kB.

I haven't checked if the size does have any influence yet.
I just wondered why I can't see any md_image with 'lsmod' and EFI
loader.

Btw, I forogt to mention I'm running 11-stable from this week, tested on
real HW and ESXi guest.

Thanks,
