Dear SL gurus,

Our SL4 AFS clients are unable to update to latest kernel, the error is

Transaction Check Error:   package
kernel-module-openafs-2.6.9-78.0.13.EL-1.4.7-68.2.SL4 (which is newer than
kernel-module-openafs-2.6.9-78.0.13.EL-1.4.7-68.SL4) is already installed
  package kernel-module-openafs-2.6.9-78.0.13.ELsmp-1.4.7-68.2.SL4 (which is
  newer than kernel-module-openafs-2.6.9-78.0.13.ELsmp-1.4.7-68.SL4) is
  already installed

Can someone advise on the fix? 
I've tried yum clean all; yum update - same error (wasn't likely to work, 
but -)

Also tried change /etc/yum.repos.d/sl-errata.repo & sl.repo to point from our  
SL4.4 & 4.5 mirror to using SL's own repos (in case the problem is our
mirror server), yum clean all, yum update - same error

On one SL4.4 afs client (where it isn't critical that AFS works), openafs was
removed, then yum update worked, but now can't reinstall openafs - it wants
kernel 2.6.9-11 installed! Why??
