Description
We need debug symbols in the .ko objects:
ubuntu@sepia12:~$ objdump -rdS /lib/modules/3.1.0-ceph-08929-g15a2015/kernel/fs/ceph/ceph.ko | head -n 100 | tail -n 10
c8: R_X86_64_PC32 destroy_workqueue-0x4
cc: 48 8b 7b 48 mov 0x48(%rbx),%rdi
d0: e8 00 00 00 00 callq d5 <destroy_fs_client+0x35>
d1: R_X86_64_PC32 destroy_workqueue-0x4
d5: 48 8d 7b 58 lea 0x58(%rbx),%rdi
d9: e8 00 00 00 00 callq de <destroy_fs_client+0x3e>
da: R_X86_64_PC32 bdi_destroy-0x4
de: 48 8b 7b 30 mov 0x30(%rbx),%rdi
e2: e8 00 00 00 00 callq e7 <destroy_fs_client+0x47>

No progress on this. I have a vague memory that someone
else might have looked at this problem a while back (Dan?).
Maybe if we get someone tasked with sustained focus on our
build and packaging procedures this can get resolved.

the symbols are there. the trick is for objdump to find them in the original path. do this:
sudo mkdir -p /srv/autobuild-ceph/gitbuilder.git
sudo ln -s /path/to/your/kernel/tree /srv/autobuild-ceph/gitbuilder.git/build
and objdump -rdS foo.ko will be wonderfully useful once again.
