Song requested " /proc/<pid>/stack for <pid> of md1_raid6? We may want

One difficulty is that this is the upstream list; and kernel 5.5 is
end of life. Ordinarily older kernels are distribution responsibility.
Upstream development is mostly interested in current stable kernels at
the oldest, and mainline development kernels. But hopefully someone
will still have an idea what's going on, if it's a bug or possibly
misconfiguration.
