[Crash-utility] kmem -[sS] segfault on 2.6.25.17

[Mike Snitzer]

I'm getting a core when I try to show slab data (kmem -[sS]) on
2.6.25.17 with both a live crash or saved vmcore.

The core shows that the segv is coming from memset() via
gather_cpudata_list_v2_nodes (memory.c:10119).  This is with crash
4.0-7.4, but the same crash occurs with crash 4.0-6.3 (memory.c:10108)
and older.

I've also seen kmem -[sS] segfaults with older kernels too (e.g. 2.6.22.x).

Have others experienced this?  Would it be useful for me to provide my
kernel config?
