We've seen a number of reports for liveusb images that spit out those
printks, but seem to otherwise work fine.

Even if the devices need cache flushes, what is a typical user supposed
to do about that?  I'm not particularly tied to this patch, but there is
nothing a normal user can do with the information spit out by these
printks, so making it KERN_ERR seems excessive.
