+
+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
+(https://www.mageia.org/pipermail/mageia-dev/2012-February/011709.html),
+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.
