Hi Chris, hi all, case closed. The reason was that some NVMe devices weren't recognized. I don't have any idea **why** this happened, but I cleaned out the whole models tree, made a complete rebuild of the kernel, and now it works.
Sorry for the noise. And I also switched to dracut on the go, thanks for the suggestions. Best Norbert -- PREINING Norbert https://www.preining.info Fujitsu Research Labs + IFMGA Guide + TU Wien + TeX Live + Debian Dev GPG: 0x860CDC13 fp: F7D8 A928 26E3 16A1 9FA0 ACF0 6CAC A448 860C DC13
