On our UV systems, this really is redundant information and adds noise to the console printout. If you need to examine it, dmesg will provide it (or don't use the limit_console_output flag)?
I had thought of some reduction techniques to reduce console output, but it didn't seem worth the complexity. Perhaps I was wrong?
