OS: Ubuntu22.04

Kernel-config: 5.15-52 (fetched from ubuntu22.04-5.15.0-52, GCC-11.2.0)

Step,

1, Git clone crash sourc code

$ git clone https://github.com/crash-utility/crash.git

2, Change crash source code to workaround version match verification

diff --git a/filesys.c b/filesys.c
index c2ea78d..b62d086 100644

3, Build crash

$ make

4, Fetch vmlinux (with CONFIG_DEBUG_INFO enabled)

5, Start crash

$ sudo ./crash ./vmlinux /proc/kcore

6, If need crash for kernel crash usage, please install kdump-tool or kexec-tool and enable crash catch.

$ sudo ./crash ./vmlinux /var/crash/202210241024/dump.202210241024
