WARNING: Because this kernel was compiled with gcc version 4.1.1, certain
         commands or command options may fail unless crash is invoked with
         the  "--readnow" command line option.


Using --readnow also results in the same error. There is no error when using
crash-4.0-4.1 and crash-4.0-4.2

So, it would be useful to have the newer crash rpm packaged with RHEL5RT.

Marking as fixed with the later version of crash.  Will mark as accepted once
RedHat includes in the repository.

Sripathi, yes. The required version of crash tool is available in RHEL5.1. We
can close this bug.
