Hi,

I'm debugging linux kernel version 3.12.8 (x64) with gdb, through a
pts console with KVM

%> gdb --version
GNU gdb (GDB) 7.7.1
%> gcc --version
gcc (GCC) 4.9.1

When I set a breakpoint with 'b' command, it works.

But all parameters value are incorrect. I added printk to testify, and
it was indeed incorrect

Anyone know how to fix that?
