Hi everyone, my wifi module can run successfully on linux 2.6.18, but when I load the module
insmod rt5370sta.ko
The following occurs:

What is more: If I don't plug the wifi module, I can load the module successfully,.If I plug the wifi module, the above problem occurs.
The problem is the same module can work well on 2.6.18 kernel, so that indicates the module code has no problem. I doubt the 2.6.37 kernel has some problems.
Can anyone help me?
