It means: - you don't have the latest kernel (which indicates which driver ran into the problem) - The driver has a bug in its devstat implementation. I know for sure that there are problems in the wd driver w.r.t. devstat. Mike hasn't been able to track them down, though. Don't worry, it's not a harmful bug, it just means that your disk statistics will be a little off. I plan on disabling this warning before 3.0, so people don't get confused, upset, distraught, etc. over it. I'll re-enable it after 3.0, though. It has exposed bugs in the devstat implementation of several drivers that might not have been found otherwise.
