Comment 46 for bug 802626

As mentioned, the long delay at boot is definitely experienced by users including me that have their root fs on LVM. The --no-udevsync workaround fixes the issue that apparently started with the update to 3.00-14. Personally, I suspect that some problem was present even before 3.00-14 but occurring so rarely that one was not noticing it (e.g. 1 slow boot every 100). With 3.00-14 the hang at boot became sistematic.

As the original reporter of Bug #902491, I really hope that it can get some attention (e.g., currently this bug has a 'high' importance and that one a 'medium' one and most important this thread seems to host a technical discussion). Note that all those on 902491 see that the --no-udevsync workaround fixes the issue. Also note that following a (possibly wrong) hint on my side 902491 was closed as a duplicate of the current bug.

For the time being, following the comment by Steve I am re-opeining 902491 by removing the duplicate status. Please let me know if it is more appropriate to leave 902491 closed and open a new "vgchange may deadlock in initramfs when VG present that's used for rootfs"
