suspect this is a duplicate of bz 490818.  Please test with the rpm found here:
http://people.redhat.com/nhorman/rpms/kexec-tools-1.102pre-69.el5.x86_64.rpm
and see if the problem is resolved.  Thanks

Thank you!
"kexec-tools-1.102pre-69.el5.x86_64.rpm" works!
Comment 5 Neil Horman 2009-05-12 14:27:21 UTC
