| Doc Text: |
Cause: devel packages contain two executable files: scripts/conmakehash and scripts/pnmtologo that are never changed between kernel variants and generate the same hash value for all variants.
Consequence: debuginfo conflicts occur on these files
Fix: remove these files from the -devel packages since they are not used in generation of kernel modules.
Result: No debuginfo conflicts

Just clarifying, the conflict happens between these two packages:
kernel-rt-trace-debuginfo
kernel-debug-debuginfo
Ok, can we please come up with a list of steps to reproduce this? It looks like you have to install the kernel-debuginfo stuff from a lookaside repo? There seem to be two files that cause conflicts:
scripts/conmakehash
scripts/pnmtologo
Both are executables that are compiled when the BuildKernel macro is invoked.
We Since the first comment from David, I've seen the conflict shift from the trace kernel to the vanilla kernel. I suspect we're hitting some corner-case in the debuginfo generation script.
My solution so far is to go into the kernel-rt script, in the definition of the BuildKernel macro and add the following change:
diff --git a/MRG/kernel-rt.spec b/MRG/kernel-rt.spec
index de6b22a..8b7e88d 100644

Just build the kernel-rt-3.2.23-rt37.55.el6rt package and it seems to avoid the conflict issue.
