I finally figured out how to make objdump interleave the source code in the .ko file dumps on our qa machines. The problem is that the debug info refeferences the path where the kernel was compiled (which is non-obvious since the info is compressed). For our environment, this is a quick workaround: sudo mkdir -p /srv/autobuild-ceph/gitbuilder.git sudo ln -s /path/to/your/kernel/tree /srv/autobuild-ceph/gitbuilder.git/build objdump -rdS whatever.ko | less Now, to figure out why kdb freezes on the 'dmesg' command... sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
