Probably yes. I have seen those kernel messages less frequently than once per day on average. "Rule of Least Confusion" does suggest that unless this really reports about something being wrong, it should not report it -- if it is generated because the coder was unsure of what will happen, then the kernel needs more pacthing. Current server uptime is 54 days, which means the kernel may have already been patched somehow regarding this. /Matti Aarnio
