[Crash-utility] problems running crash on recent rawhide live kernels

I was trying to run crash against a live rawhide kernel and am getting some errors when I try to start it: crash: invalid task address in pid_hash: ccccccccccccca84 crash: invalid task address in pid_hash: ccccccccccccca84 ... crash: invalid task address in pid_hash: ccccccccccccca84 crash: cannot gather a stable task list via pid_hash (500 retries) ...and then crash exits. There are a few messages in dmesg: crash memory driver: version 1.0 crash memory driver: !page_is_ram(pfn: 61000000c) Relevant packages: kernel-2.6.24-0.62.rc3.git5.fc9.x86_64 kernel-debuginfo-2.6.24-0.62.rc3.git5.fc9.x86_64 crash-4.0-4.10.x86_64 ... the host is a FV xen guest (but that shouldn't matter, should it?). I'm hoping I'm just doing something wrong, but I don't see anything right offhand. -- Jeff Layton <jlayton(a)redhat.com&gt;
