I tried the suggestions on the page you metioned. Unfortunatly, they
do not help in this situation.

- The rootdelay=X option does as advertised: "Also it adds time to
scsi device to settle before calling mdadm or lvm thus excluding
potential races.".
In this situation, I seem to need a delay between assembling mdadm and
activating the VG's.
- scsi_mod.scan=sync does not introduce any visual delay, but doesn't
help me either.
- I've also tried a couple of break= commands, but there doesn't seem
to be a breakpoint between mdadm and LVM.

Thank you for the suggestion.
