The file system warning us that the sata disk it was talking failed an IO. However, this is likely to be some other issue with the SATA controller. Can you post more details about the config? o "lspci -v" o hdparm -i /dev/sd I don't expect I'll know what's wrong, but just want to document the bug. thanks, grant > Hopefully this will be more useful. > > Guy >
