I'm fine > with adding it to the patch, but if nobody is going to use crash on > s390x I'm curious if we should leave it enabled. crash itself is maintained by IBM for s390x, so I guess we should keep all arches the same when possible. Kyle probably has more information. I just tried the command from rhbz#492803 crash -d7 /usr/lib/debug/lib/modules/3.13.0-0.rc1.git2.1.fc21.s390x/vmlinux on kernel with the crash driver enabled and it works if I can see.
