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? Mike
