If I compile a kernel with a recent binutils and the scc driver
I get the now famous linking error:
net/network.o(.text.lock+0x2b38): undefined reference to `local symbols
in discarded section .text.exit'
Stock 2.4.17 kernel source, GNU ld version 2.11.92.0.12.3 20011121.

output of Keiths reference_discarded.pl would be useful.

Hmm, bugger. It's nog even the SCC driver as I guessed:
[maltimi;~/linux]-36> perl ../reference_discarded.pl
Finding objects, 443 objects, ignoring 0 module(s)
Finding conglomerates, ignoring 37 conglomerate(s)
Scanning objects
Error: ./net/ipv4/netfilter/ip_nat_snmp_basic.o .text.lock refers to 0000004c R_386_PC32 .text.exit

Yup, was just going to ask if you were compiling netfilter options
statically or modularly. I've gotten the same error (as has Adrian
Bunk and perhaps countless others) by compiling them in statically,
so for now I just compile them as modules.

Yep, the broader problem of lock handling in discarded sections leaving
dangling references in section .text.lock. See [patch] 2.4.18-pre1
replace .text.lock with .subsection.
