此故障实际上导致 大别山T2218A 服务器无法安装任何新世界系统.

MarsDoge commented 8 months ago

@KFERMercer Node0节点不支持内存不在位，必须保留内存，在此基础上请确认是否在配置界面是否已关闭legacymode模式引导社区版系统.

KFERMercer commented 8 months ago

@MarsDoge 感谢回应

Node0节点不支持内存不在位，必须保留内存

后续尝试只插 A2 (也归属于node0) 依然无法加载内核, 故障同描述中 A1 插有内存的情况.

在此基础上请确认是否在配置界面是否已关闭legacymode模式引导社区版系统.

此版本固件无 legacymode 配置选项.

MarsDoge commented 8 months ago

验证 archlinux-livecd-2023.11.29-loong64.iso 如下: 目前看似是最新的内核可能启用了某些配置，导致搭配旧一些的固件引导出现了calltrace，请补充一下您内核打印的完整log. @KFERMercer 或者您可以是否方便尝试一下6.1的内核，感谢！
