Description of problem: rc2版本iso下，kdump服务开启失败 Version-Release number of selected component (if applicable): iso下载： https://mirrors.openanolis.cn/anolis/8.8/isos/RC2/loongarch64/anolis-8.8-loongarch64-dvd.iso How reproducible:100% Steps to Reproduce: 1.安装并启动RC2版本iso 2.查看kdump服务的状态 systemctl status kdump Actual results: systemctl status kdump ● kdump.service - Crash recovery kernel arming Loaded: loaded (/usr/lib/systemd/system/kdump.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Fri 2022-11-18 11:21:36 CST; 1 months 24 days ago Main PID: 640812 (code=exited, status=1/FAILURE) 11月 18 11:21:36 bogon systemd[1]: Starting Crash recovery kernel arming... 11月 18 11:21:36 bogon kdumpctl[640812]: kdump: Error: No find /boot/vmlinux-4.19.190-6.5.lns8.loongarch64+kdump kernel file 11月 18 11:21:36 bogon kdumpctl[640812]: kdump: Please specify DEFAULT_KDUMP_KERNEL configuration in /etc/sysconfig/kdump file 11月 18 11:21:36 bogon kdumpctl[640812]: kdump: failed to prepare for kdump bootinfo. 11月 18 11:21:36 bogon kdumpctl[640812]: kdump: Starting kdump: [FAILED] 11月 18 11:21:36 bogon systemd[1]: kdump.service: Main process exited, code=exited, status=1/FAILURE 11月 18 11:21:36 bogon systemd[1]: kdump.service: Failed with result 'exit-code'. 11月 18 11:21:36 bogon systemd[1]: Failed to start Crash recovery kernel arming. Expected results: kdump服务正常
kdump服务状态现更新如下： systemctl status kdump ● kdump.service - Crash recovery kernel arming Loaded: loaded (/usr/lib/systemd/system/kdump.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Mon 2023-01-16 09:45:05 CST; 4s ago Process: 24195 ExecStart=/usr/bin/kdumpctl start (code=exited, status=1/FAILURE) Main PID: 24195 (code=exited, status=1/FAILURE) 1月 16 09:45:05 bogon systemd[1]: Starting Crash recovery kernel arming... 1月 16 09:45:05 bogon kdumpctl[24197]: kdump: No memory reserved for crash kernel 1月 16 09:45:05 bogon kdumpctl[24197]: kdump: Starting kdump: [FAILED] 1月 16 09:45:05 bogon systemd[1]: kdump.service: Main process exited, code=exited, status=1/FAILURE 1月 16 09:45:05 bogon systemd[1]: kdump.service: Failed with result 'exit-code'. 1月 16 09:45:05 bogon systemd[1]: Failed to start Crash recovery kernel arming

针对最原始的问题， >11月 18 11:21:36 bogon kdumpctl[640812]: kdump: Error: No find >/boot/vmlinux-4.19.190-6.5.lns8.loongarch64+kdump kernel file >11月 18 11:21:36 bogon kdumpctl[640812]: kdump: Please specify >DEFAULT_KDUMP_KERNEL configuration in /etc/sysconfig/kdump file 如上失败是因为没找到kdump内核，所以kdump服务失败。 原因是loongarch的实现和x86/arm64架构不一样，针对于kdump操作，需要编译两个不同的内核，一个是生产内核，一个是捕获内核，而不像arm64它们那样只需要一个内核就可以。 之后修改计划： 内部产品正在重新重写kdump功能实现，计划实现同一套二进制方案，之后就可以类似于arm64那样，生产内核和捕获内核可以是同一个，但修改比较大，需内部评审通过之后再修改anolis上的内核。 当内核修改完成之后，再修改kdump服务，并同步更新kexec-tools和crash工具。 完成以上所需工作，需要一定的时间。 > 1月 16 09:45:05 bogon kdumpctl[24197]: kdump: No memory reserved for crash > kernel 而显示如上问题，大概率是crashkernel参数使用的不对，导致预留crashkernel空间失败。

暂不解决，GA发布时Release Notes
目前龙芯kdump服务需要另外一个转存内核，龙芯方面正在进行开发向通用做法靠拢，预计在8.8中无法支持。
