Hi John,

Here is a patch for gdb 6.6 that fixed the problem for me. There are two 
patches, and below is the spec file I used (with Freescale ltib and kernel 
2.6.29).

Regards,
Lars

%Description
%{summary}

Notes:

This gdb package is built using gdb-6.6 plus the gdb patch from the
CodeSourcery %{cs_version} release: gdb-%{cs_version}-from-fsf-6_6.diff

The gdb tarball can be obtained from any of the GNU ftp sites or their mirrors.
The CodeSourcery patch can be obtained by downloading the source rpm:
freescale-powerpc-linux-gnu-%{cs_version}.src.rpm from:
http://www.codesourcery.com/gnu_toolchains/power/download.html and then
extracting the gdb patch from this source rpm.

requires: libtermcap and ncurses
