Hi Dave,
I tried to run crash on Fedora 8's kernel 2.6.24.3-12.fc8 x86_64, and
it has errors that look like the following:
[...]
crash: duplicate task in pid_hash: ffff81012f0811d0
crash: duplicate task in pid_hash: ffff81012f0811d0
crash: duplicate task in pid_hash: ffff81012f0811d0
crash: duplicate task in pid_hash: ffff81012f0811d0
crash: duplicate task in pid_hash: ffff81012f0811d0
crash: cannot gather a stable task list via pid_hash (500 retries)
I ran crash with -d7, and uploaded the log for debugging:

Thanks,
