It is not about whether it is important or not - the question is whether
changing existing functionality which someone might rely upon is a
problem here? Someone might be expecting exactly those messages to
appear in dmesg.
Pulling in a couple more people who have been touching error reporting
code in the last year or so (Hi Lance, Naveen ... feel free to drag more
people to look at this thread).
I prodded Chen Gong in to make this change because our console messages
are way to verbose (and scary) for simple corrected errors. There are 18
fields in the memory error section (as of UEFI 2.4 ... more are likely to be
added because there are issues that some of the 16-bit wide fields are too
small to handle increased internal values in modern DIMMs). Whether you
print that one item per line, or a few very long lines - it is way
more information
than the average user will ever want or need to see.
