Updated crash packages that fix a bug are now available for Red Hat Enterprise Linux 5.
The crash packages contain a self-contained utility that can be used to investigate live systems and kernel core dumps created by the netdump, diskdump, and kdump utilities.
The Xen dom0 dump files created with the "makedumpfile -d1" command on very large systems could create an ELF vmcore that the crash utility incorrectly determined to be an old-style netdump vmcore. Consequently, the crash session failed during initialization with the error message "crash: cannot read xen kdump p2m mfn page". With this update, the code has been fixed and the crash utility now properly starts in the described scenario.
Users of crash are advised to upgrade to these updated packages, which fix this bug.
