I successfully insert some function into the kernel code and make it

prompt the user, and let the user input a command(maybe a comment to
display the current time. Something like a shell would do) and interact ?
(I had checked the "sys_***" functions in this page:

but just can't find a proper one )

Hi...
sounds like what kgdb does. But not sure if it is still maintained or not.
btw, kernel can not be paused, actually. if you really need that, you need to run linux kernel inside virtual machine and pause the virtual machine. But doing that, you will also pause user space too :)
