After a recent upgrade of a Debian system, I discovered that
systems weren't rebooting; they would always halt in the automatic
fsck of other file systems.
Upon investigation, it turned out that fsck didn't understand the
kernel "root=302" parameter and was trying to run e2fsck on the root
file system. This produced an error, causing the boot process
to drop into a recovery shell.
System is i386, current Debian sid (unstable). But I compiled
util-linux from the git sources to eliminate Debianisms from
the problem.
Running the v2.28-rc1 release (8c97556ecfc0af358d35dc7a842aaadde5eeafd3)
I got some compile warnings (appended for reference), but a
working execurable which could be run as follows:

I'm not quite sure where in the code this is *supposed* to be parsed
so I haven't found the bug yet. It *used* to work, but I fear it's
been months since my last reboot and I don't have a list of everything
that changed.

The details from config.log look more like a problem with the headers
rather than util-linux, but it says report it, so I am:
