As I've said before, I really do not think this is anything to do with
number of cores. I do see that there is a chicken and egg problem, but
why would the number of cores affect this? Nothing runs in the
background here.
As stated earlier
(<A HREF="https://www.mageia.org/pipermail/mageia-dev/2012-February/011709.html">https://www.mageia.org/pipermail/mageia-dev/2012-February/011709.html</A>),
the problem is simply that there are no calls to wait_for_dev for the
lvm drives and thus the whole initqueue stuff just glosses over things
and doesn't ever activate them.
What is different to the last time is that now for hostonly initrds (not
the one you generated), the wait_for_dev call WILL be added. I had hoped
this different approach would have fixed your problem.
However, due to me now doing this fallback non-hostonly initrd, the
original problem still manifests itself.
Can you test that generating a new initrd after booting via dracut (and
thus getting a hostonly one) does actually activate your usr partition?
I'm not 100% convinced there will not still be a problem with the
"resume" support and swap partitions, but it will hopefully give you a
smooth boot even if resume support is busted.
The non-hostonly problem does need a fix and I'll see what can be done.
