Hi Sharyathi, With the "limit/readmem()" fix to max_cpudata_limit(), an additional check in gather_cpudata_list_v2_nodes() to make sure that the multiple-index list doesn't get overflowed, and a few cosmetic mods, this patch looks good to go. (No further patch is required.) Nice work -- this part of the crash code has always been a huge PITA to keep functional... We're overdue for a release -- but it would be nice if you can come up with a reason for your arithmetic bug in "kmem -i". Like I said, it works OK for me on x86 and x86_64. Let me know what you find. And again, multiple thanks for undertaking this "kmem -s" effort. Dave
