Hi David, I recently tested makedumpfile on ARM64 with 3level-4K, 3level-64K and 4level-4K page tables. I tried to analyze the dumpfile with the crash tool. I noticed that with 3level-64K and 4level-4K I got the following error when I tried to run "kmem -f" : kmem: invalid kernel virtual address: ffff************ type: "first list entry" I did not see the above error with 3level-4K. Also, on all three combinations, other commands (bt,dmesg etc) ran fine. Are there any plans to add support to the crash tool for these additional kernel configurations? -- Thanks, Azriel Samson Qualcomm Innovation Center, Inc.
