I don't recall reports of any similar problem with any upstream versions of
this code but it's trival to perform this specific test to double check that.
Meanwhile I suggest you check your udev rules aren't messed up.

This rule needs to fire to clear the semaphore:
95-dm-notify.rules:ENV{DM_COOKIE}=="?*", RUN+="$env{DM_SBIN_PATH}/dmsetup udevcomplete $env{DM_COOKIE}"

Upstream is here:
