While I can reproduce occurence of the error on boot indeed, I was not able to reproduce the remaining parts of your report, i.e. repeatedly logging of the error on boot. Can you share more details on your setup, have you NFS shares automounted or mounted in fstab? Other NFS dependencies wich trigger early on boot? Regards, Salvatore
