[CentOS] Latest kernel produces kernel error on Dell R200 on boot-up
I accidentally noticed this error written to the warn log on my Dell R200's when the machines booted up after latest kernel update. Google doesn't have this exact error, only a few with differently named devices, but all seem to have to do with USB. Could this be a bug? Didn't see this error on other machines with more than one USB port, though.
