When compiling 2.5.5-dj2, I am still getting a .text.exit linker error:
drivers/net/net.o(.data+0x1274): undefined reference to `local symbols
in discarded section .text.exit'
I am using Debian unstable, binutils 2.11.93.0.2:
ii binutils 2.11.93.0.2-2
I can get it to link if I follow the directions that the Debian
maintainer has been giving out (deleting the .text.exit line from
vmlinux.lds) but that isn't the right solution, and I don't have the
abilities to actually fix it. My ver_linux output is appeneded at the
end. Thanks in advance.

Can you grab http://kernelnewbies.org/scripts/reference_discarded.pl
and post the output ?

Run this script to identify the offending object in net.o then contact
the object maintainer.
