Big time. I've gotten very good over the years at diagnosing and fixing issues using log messages. But sudden

Hi David,
Looking at your http://darose.net/ServerCrash20220209.png, are you aware
of https://www.kernel.org/doc/Documentation/RCU/stallwarn.txt which has
detail on what it means? Though it looks to me like at least one line
of output has been trampled.
Also, one Google'd suggestion was a real-t

I suppose it could also be southbridge being annoying - did you check
temps on the mobo are reasonable to be sure of adequate cooling? Are you
overclocking at all by chance?

Thanks much for the response. I'm not really clear what specifically
that might mean though: A buffer in the kernel? In an application?
And how might I debug that and try to prevent it from happening again?
Thanks,

Basically server just completely freezes up - doesn't respond to pings,

Good news is:

Does your server support IPMI and thus SOL (serial over LAN)?
Thanks for the suggestion. Unfortunately this is just a home/desktop
server, so I don't think its mobo supports IPMI.
Thanks,

A couple of weeks ago, my entire home network went dead right in the
