Kernel panic - not syncing: Fatal exception in interrupt

linux内核运行出现这种问题错误怎样分析与解决，希望专业搭救一下，新手不懂啊,不知从何处入手。

[runsunlg]

查一下你的某个内核中断是否调用了print或内存分配类的有阻塞动作的系统调用函数

[Creator_莫言]

PC is at __rcu_pending+0x40/0x41c 先通过运行arm-linux-gdb vmlinux命令运行gdb工具，定位__rcu_pending+0x40出错在哪个文件 Code: e59f73cc e5910014 e5971000 e59530b4 (e596c018) 再用arm-linux-objdump 命令反汇编对于文件的.o文件，对比code中的地址就可以找出错误的地方。 以上可以定位出错点，具体如何改还要你自己看

[猪头三小队长]

大概是你的软中断处理函数中访问非法地址了。 printk是原子上下文安全的函数，可以排除这一点。
