Not reproducible with arm64-targeted 7.3.0 and 7.3.1++ crashes built on x86_64 with my old arm64 vmcore. ``` crash-arm64> search -t ffff000014f0f760 PID: 8807 TASK: ffffdc64479fdc00 CPU: 2 COMMAND: "bash" ffff000014f0f700:...

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?

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...

Do you need the System.map file? Please see `mapfile` on the man page. (It looks like crash-7.3.0-3.fc35 does not have 68870c83d299603c07785e3530e33c13045c87ef, so cannot be used for 5.16 in the first...

Oh sorry, I completely missed this. I've just posted the patch to the mailing list [1]. I will check it later. [1] http://lists.infradead.org/pipermail/kexec/2022-November/026248.html

makedumpfile has to use only the `__arch__` style to enable TARGET build, e.g. `make TARGET=mips64` on an x86_64 machine. Your build environment has `-D__mips64el__`, so does this work for you?...

It sounds possible, although personally I prefer to use gzip somehow if possible. If you have a patch, please post it on the kexec mailing list at: http://lists.infradead.org/mailman/listinfo/kexec I won't...
