? 5.5 ?
centos 5.5 hit "end of life" back in April
at that time you needed to upgrade to 5.6
5.6 now is "End of Life" and needs to be upgraded to 5.7
CentOS ONLY supports the Current version and DOSE NOT back port to old versions like Red Hat dose
How did you install this "driver"
undo what you did to uninstall
and UPGRADE to the current 5.7
see the CentOS wiki
