Recent arm64 kernels may need -m vabits_actual=xx and etc. especially if it's a ramdump. What is the kernel version and CONFIG_ARM64_VA_BITS?

sensarliar commented 1 year ago

uname -a

Linux localhost 4.14.186+ #1 SMP PREEMPT Thu Mar 9 18:01:42 CST 2023 aarch64 zcat /proc/config.gz |grep CONFIG_ARM64_VA_BIT CONFIG_ARM64_VA_BITS_39=y

CONFIG_ARM64_VA_BITS_48 is not set

CONFIG_ARM64_VA_BITS=39

add "-m vabits_actual=xx" , does not work.

The "-m vabits_actual" option cannot be used for that old kernel (< 5.4), please don't specify it. What is the output of crash -d 1 vmlinux vmcore?

And please use code blocks [1] for log... [1] https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/creating-and-highlighting-code-blocks

crash-7-branch image is good to load dumpfile; but master branch is not good. it is a bit weird.
