Your patch is suppressing information that I want to have and my console can handle, just because your console is slow, even though there is no need to use that console at that log level. NAK to your patch. I think you're looking at this from the wrong angle. A console that takes almost 4 minutes to print 70k lines shouldn't be the baseline for how verbose KERN_INFO is.
