Yes, there is something wrong with your kernel code. The oops will
tell you what went wrong.

Reading Documentation/oops-tracing.txt is a good start.

About kernel panic!

[Zhenyu Wu]

Hello, Everyone,

I think i have met lots of troubles when i am programming in the kernel, so, i
want to get
some help.

One of my troubles is that, sometimes, the program can work well, but sometimes,
there are
kernel panics. So, does someone else meet such questions, what is the major
reasons? From the
indication of the log messages, i can find the messages on allocting the memory, i
remember, 
i use the kmalloc to do it, but is there something wrong? 

Thanks,

Do you mean that there is something wrong with my Kernel Code? So, i have to use a
new kernel code, but i can't understand why.

Thanks and Best,

Well for anyone to answer it would be best if you post your code.
Otherwise no one can help you.
