Spose so.  Some additional words explaining why you think this would
result in an improved kernel would help here.  Are you seeing
misdirected problem reports?  Are we missing out on opportunities to
fix hardware?  What is driving for this change?  Will it bring out some
improvement in something which you're seeing within Intel or was it
just a random hey-lets-try-this thing?

The kernel's whole approach to messaging is pretty haphazard and lame
and sad.  There have been various proposals to improve the usefulness
and to rationally categorise things in way which are more useful to
operators, but nothing seems to ever get over the line.

I'm trying to think of a rational reason for capitalising "Error", and
failing.

Oh well, that's what the other strings do and the kernel already stands
as a punctuation/grammar how-not-to guide. ho hum.
