You might consider trying the main line 2.6.9-22.0.2.EL (or
2.6.9-22.0.1.EL) kernel and the kernel-module for xfs in our testing
repo (if the only reason you are using the centosplus kernel is xfs).

This xfs code is from SGI and is a newer than the code in the 2.6.9

When CentOS-4.3 is released, the new modules will be released in for the
centosplus kernel and there will be modules to run xfs on the main line
kernels as well.
