Hello. 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 av.
