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:
[Crash-utility] [PATCH] runq: search current task's runqueue explicitly

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.
Thanks,
Dave
