You only see messages and logs from node0, because the cpus there are
the only ones that see any errors logged in their banks.

The cpus on node 1, 2, 3 scan all banks and find nothing, so say nothing.
There are no system-wide banks ... just core-wide (in recent generations
banks 0-3) and socket-wide (banks >=4).  But don't code those numbers
into any generic code ... we will change them sooner or later.
