You cannot be sure 99% until you can reproduce the problems...

I have been running 2.6.18-92.1.22.el5.centos.plus both on my own
workstations and as VMware guests. The real (host) machine works as
an nfs server as well. I have never seen any issue there.

I have not seen this behavior either on any of the machines running a
centosplus kernel.

Unless this can be reproduced by you or other users, it will be very
difficult to even identify it as a bug. Troubleshooting is nearly
impossible. The centosplus kernel has several drivers and other
options enabled, but otherwise its behavior should be the same as the
distro kernel. Yes, some of those options might be involved, but
nothing is immediately obvious as to the cause of the issues you
experienced.
