ok. Thanks a lot.
And also, when I compiled the kernel, there is a warning:
{standard input}: Assembler messages:
{standard input}:70: Warning: setting incorrect section attributes for .got
do you think it is related to my problem? Thanks again.
Bests,

You've probably messed up somewhere in your hacking of the kernel. I
would guess you're trying to deference a null pointer to a struct.
The remote gdb functionality in m5 may be helpful to you. It
hasn't been particularly tested in v2.0b however.
