Hello John,


What you have seen are kernels of differents versions.

  kernel-2.6.18-92.1.10.el5.x86_64       : up to date.
  kernel-2.6.18-53.1.21.el5.JSP1.x86_64  : obsolete.
  kernel-2.6.18-53.1.19.el5.JSP1.x86_64  : obsolete.

I could have built a newer one with a version incremenent
that would have been greater than the latest (NFS lockd) released,
but this would mix up with the SL/TUV kernel versioning.
That is, my "newer" kernel could get in the way and block
updates from the distrib.

So I made a "variant", that is another kernel but with the
same version, so it do get in the way of the updates.
Besides, it allows to revert to the up-to-date stock kernel
in case of unexpected problem.

Unfortunately, we uses our NFS shares with the "nolock" option
(my fellow sysadmin managing the servers under BSD, tells me 
 that the lockd algorithm is intrinsistically flawed and do
 not want to uses it). So I haven't tested it yet.

I've made this kernel avalaible because I took me little time
(automated procedure...) and some people seemed to be stuck
by this bug.


Best Regard,
