Here is a patch against crash v6.0.2 that adds duplicate node detection
per-CPU for the CFS runqueue display in dump_CFS_runqueues() for the
runq command.
This resolves the failure to bail-out of the unending looping display I
get with the crash dump I have that has a corrupted CFS runqueue
containing a loop.

That was quick!
I'm going to have to re-work this patch slightly because of the queued
changes for crash-6.0.3 that are based upon Daisuke's runq patch:
[PATCH] runq: search current task's runqueue explicitly
https://www.redhat.com/archives/crash-utility/2012-January/msg00009.html
Dave,
On second thought, I'd rather have you update your patch accordingly, and
then test with your dumpfile to make sure it works as planned.
Can you do this:
$ wget http://people.redhat.com/anderson/crash.tar.gz
Then go into any top-level crash utility source directory, and do this:
$ tar xvzmf /path/to/crash.tar.gz
which will overwrite everything -- just "make" to rebuild with all
the queued crash-6.0.3 changes to date.
Then re-do your patch to task.c, test it, and re-post it.
Dave,
I've got a patch prepared but I can't test it until my morning tomorrow
(02/02) so I'll post it then. I'm sorry for the delay.
