Hello Colin,

When using gdb to debug Linux kernel, I found that it cannot be stopped
temporarily by using "ctrl+c".
After the first strike of "ctrl+c", nothing happen.
After the second, Linux kernel will show these messages:
   Interrupted while waiting for the program.
   Give up (and stop debugging it)? (y or n)
If choose yes, kernel will totally stop and it goes back to gdb shell.
How can I stop kernel temporarily and then resume it?

You should use the following command in GDB:

   set remotebreak 1

After that it will start to behave as you expect it to, i.e. it will interrupt the kernel as soon as you press CTRL-C.

Happy hacking,
Vladimir
