Kernel panic - not syncing: Aiee, killing interrupt handler!

检查是否引用了空指针？
|
关注，以前高低温时出现过这种问题，发现是硬件的事，但反应出来的现象肯定是程序调用的不该使用的地址，例如对空指针操作，或错误的地址操作
|
除非是驱动程序，否则一个空指针或野指针就能让内核崩溃，那Linux就是dos的水平
|
看不懂的路过，估计需要高手才能解了
|
根据这条语句Unable to handle kernel NULL pointer dereference at virtual address 00000000，以及后面关于page的打印信息可以看出应该是内存出了问题，backtrace的最后打印的是ioctl的相关信息，应该是跟配置相关的。不知道lz是在什么情况下出现崩溃的？

看上去是你的inc_110a 模块的ioctl操作导致的问题，可能两边同步没做好什么的，这种要结合源代码分析

在aerial g_inc_110a_driver里是否有空指针？
