Sorry, I couldn't diagnose anything properly. When it happened the
sysadmin didn't give me the panic details, and being production
machines the main priority was to put them back into service as soon
as possible.
Would it be a good idea to file a PR with such fuzzy information? I
don't think so, that's why I didn't do it. Of course I can do it if
someone thinks it's worth. But unfortunately I cannot get more
precise details.
