(2.5.5-dj2) still getting .text.exit linker errors

(2.5.5-dj2) still getting .text.exit linker errors

[James Curbo]

[note: I am not subscribed, please cc: me in replies]

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 ?

OK, here it is:

Finding objects, 513 objects, ignoring 0 module(s)
Finding conglomerates, ignoring 53 conglomerate(s)
Scanning objects
Error: ./drivers/net/de2104x.o .data refers to 00000074 R_386_32

Done

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