I need some help debugging this kernel build problem.
Here's the tail of my kernel build.
ld -m elf_i386 -r -o init.o main.o version.o do_mounts.o
make[1]: Leaving directory `/usr/src/v2.5.30/init'

A know problem with some combinations of binutils and kernel sources. As
Debian bintuils package says:
x You may experience problems linking older (and some newer) kernels with x
x this version of binutils. This is not because of a bug in the linker, x
x but rather a bug in the kernel source. This is being worked out and x
x fixed by the upstream kernel group in newer kernels, but not all of the x
x problems may have been fixed at this time. Older kernel versions will x
x almost always exhibit the problem, however, and no attempts are being x
x made to fix those that we know of. x
x x
x There are a few work-arounds, but the most reliable is to edit the x
x linker script for your architecture (e.g. arch/i386/vmlinux.lds) and x
x remove the '*(.text.exit)' entry from the 'DISCARD' line. It will x
x bloat the kernel somewhat, but it should link properly. x

Jose...
thanks for the reply. This link error happens with 2.5.27-2.5.30. Are you
sure the kernel people are working on this?

Well, it doesn't seem so.

The response seems to me like "Well, I don't care as long as the latest
(not working on some arches) gcc does..."
