6.4.0-150600 内核系统发生了 soft lockup，现在系统已经无法登录，想用 virsh dump 把内存 dump 下载用 crash 分析一下，但是找不到 debug 内核，看了一下 kernel-default-debuginfo 和 kernel-debug-debuginfo 包里的 vmlinux 都没有 text 段和 data 段，用 readelf 看了一下.data 是 NOBITS，导致无法使用 crash。所以要怎么获取正确的 debug vmlinux？
字符界面能进去吗？能进去的话尝试在 yast2 里面开 kdump 。
进不去了，所以只能通过这种方式看
用 livecd 挂载根目录，用 chroot 来开 kdump
