**一、缺陷信息** openeuler2403-LTS版本内核,源码为6.6.0-38内核启动失败,疑似pahole版本过旧导致 **内核信息:** openeuler2403-LTS版本,源码tag为6.6.0-38 **缺陷简述:** 在尝试欧拉openeuler2403-LTS分支,源码为6.6.0-38的内核时,编译正常完成,但是在SG2042-riscv服务器上启动无法加载内核模块,提示`failed to validate module [xxxx] BTF`错误信息,怀疑是因为欧拉38的内核代码可能从上游backport了一些新的修改或特性,而当前使用的pahole工具版本过旧,无法正确处理这些新的内核代码修改,导致启动失败,我们尝试将pahole工具升级到了1.27版本,升级后重新编译内核,目前启动正常。 因此欧拉38的内核编译对pahole的最低版本有一定要求,旧版本的pahole可能无法正常工作。 **【环境信息】** 硬件信息 - SG2042-riscv服务器 软件信息 - openeuler2403-LTS版本分支 - 6.6.0-38的内核
