Some questions from a kernel newbie

Hi All,

I am a newbie from China. I want to fix some bugs for linux kernel (current
version or older versions), but this is my first time to join community, I
don't know how to start... Please help me answer the following questions!
:-)

Q1, Are there some development projects for newbies? Shoud I start
development with them?
Q2, I have almost two years working experience on linux kernel development,
could I directly fix bugs for linux kernel?
Q3, Could you guys recommend a kernel version to start fixing bugs?
Q4, Where can I find some details about how to fix kernel bug?

Thanks,
Zhengwang (Royo)
