Hi. Please uname -a. What is the kernel version. Also type in crash the command with -d to print debug. That would be helpful for further investigation On Jul 5, 2018 17:51, "Mozes, Rachel" <rachel.mozes(a)intel.com&gt; wrote: Hi all, I'm an Intel employee, having a MIPS Platform running Linux OS. I enabled the kexec\kdump flow in Linux version we use and now I have vmcore memory dump, and now I'm getting into troubles.... I'm running the crash utility compiled with "target=MIPS" and getting the output: crash: read error: kernel virtual address: xxxx30fc type: "possible" WARNING: cannot read cpu_possible_map crash: read error: kernel virtual address: xxxx30f4 type: "present" WARNING: cannot read cpu_present_map crash: read error: kernel virtual address: xxxx30f8 type: "online" WARNING: cannot read cpu_online_map crash: read error: kernel virtual address: xxxx30f0 type: "active" WARNING: cannot read cpu_active_map crash: read error: kernel virtual address:xxxx0a48 type: "shadow_timekeeper xtime_sec" crash: read error: kernel virtual address: xxxxa444 type: "init_uts_ns" *crash: linux/vmlinux and vmcore do not match!* As you see the tool claims that the vmlinux doesn't match to the vmcore although the vmcore captured from the given vmlinux. When I open the vmcore with gdb from our toolchain provided by MIPS, it's successfully opened and I see that the init_uts_ns is in offset xxxxa440 instead of xxxxa444 it looks for in the crash utility. I thought that maybe the issue is we use a propriety toolchain provided by Codescape (the next link) and tried to replace the gdb packet in the Makefile - but then the tool wasn't compile, it fails in the gdb_merge step: http://codescape-mips-sdk.imgtec.com/components/toolchain/2017.10-05/ downloads.html Can you help us to understand how to overcome this issue? is there any way to replace the gdb binary that the tool uses?
