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.
