Steve, I have checked in a patch that (at least tentatively) handles the new CONFIG_THREAD_INFO_IN_TASK configuration introduced in 4.9-rc1: https://github.com/crash-utility/crash/commit/c9f932440bd06f0a3d6d3ecc30d5c670021d5e5a There are still other issues with the most recent kernels, but this patch should at least get you to a prompt.
