What to do about LORs

A 12.1/amd64 server of mine hanged several times in the last week: seen 
from the network it just stopped responding (not even to pings); turning 
the screen on it just stays black. I can switch VTs (I can confirm this 
thanks to the numlock/capslock lights), but nothing is displayed. Some 
disk activity is still happening (again thanks to HD light).

Suspecting a VFS deadlock, I turned INVARIANTS/WITNESS/etc... on and I'm 
waiting for that to happen again.

Meanwhile I'm seeing a couple of LORs while booting.
What to do about this?

A long time ago I used http://sources.zabbadoz.net/freebsd/lor.html: is 
that still active or rotting?
Since I don't see what I'm experiencing there, is it worth reporting or 
is that a deprecated thing?

Then I went to bugzilla: there are tons of reports, many looking like my 
case, but not exactly identical. Most of them just timed out: I 
understand that they might be relevanto only to a specific release or 
HEAD revision.
Is it useful to make a report there?

Or i anyone interested in seeing this in other ways?

  bye & Thanks
