Multiple breakpoint issue when debugging loadable kernel module

[Vimal <j dot vimal at gmail dot com>]

Hi,

I have a loadable kernel module, and I am facing issues when setting
breakpoints.

I am using gdb 7.3.1 from ftp://ftp.gnu.org/gnu/gdb.

1. I start the kernel under qemu-kvm and load the kernel module.  The
kernel module was compiled with CFLAGS=-O0 -g

2. I generate the add-symbol-path command by using section address
information from /sys/module/$mod/sections/.*

3. I enter the add-symbol-path command into gdb, which is connected to
qemu's gdb stub via "target remote" command.

4. After loading the symbols, I do: "info line function" and am able
to see the function name's line number.   Also, "list function" shows
the source code from the correct file.

5. I do "break function", I see this message:
    Breakpoint 1 at address (2 locations)

After the last step, if I run "info line function", I see "No line
number information available for address..."

When I type "info break", I see the two breakpoints inserted at
"function+4" and "function+31".

This error does not happen in gdb-7.1.   The reason I am using
gdb-7.3.1 is that I want to use gdb.Breakpoint from a python script.

Is there a way to fix this error?   Why are two breakpoints being set?
  This error happens across a few kernel modules that I tested.

Thanks,
