Tried to compile Linux 2.6.33, and 2.6.34-rc3 with gold. Linking succeeded, but it fails to boot, it just keeps on rebooting.
To reproduce (you can also download just the tarball, but its easier if you just clone if you want to test multiple versions): 1. git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6 2. git checkout v2.6.34-rc3 (or v2.6.33) 3. Use my attached .config on x86-64 4. Build it, I used gcc version 4.4.3 (Debian 4.4.3-7), and GNU gold (GNU Binutils 2.20.51.20100410) 1.9 gold was built from CVS, with a simple --enable-gold, make all-gold, and then copying ld-new to /usr/local/bin/ld, clearing bash's cache (hash -r), and building Linux using 'make'. 5. Try to boot it either on a real system, or with qemu-system-x86_64/kvm (recommended): kvm -kernel arch/x86/boot/bzImage On a failed boot you just see the BIOS version flashing, and no messages from the kernel. 6. Use the normal (non-gold/bfd) linker, I used GNU ld (GNU Binutils for Debian) 2.20.1-system.20100303. 7. make clean 8. make Try to boot the kernel with kvm/qemu as above. On a successful boot you should see some kernel messages, and finally a kernel panic because we didn't provide it a disk to boot from. (Note: you could also just rm vmlinux, and make bzImage, but if you keep moving from gold to system linker and back at some point it'll complain about wrong kallsyms values). This is the KVM I used, but you can try to boot the kernel with anything that would normally boot it.
