Please note that after I logged this bug I realised that the issue is not actually INSTALL_MOD_STRIP as the kernel signs the modules *after* they are stripped, so the signatures should be OK.

I believe the issue is that *after* doing the module install make-kpkg then runs objcopy on the modules to copy out the debug sections for a debug package and then uses objcopy to remove the same debug sections (along with the signature) from the ones in the main package. :-(

So currently this is affecting Raring (13.04) kernels causing them to be always tainted (I'll open a separate report to record that), thus:

chris@quad:~$ dmesg | grep -i taint
[ 2.003424] Disabling lock debugging due to kernel taint

chris@quad:~$ grep -w F /proc/modules | wc -l
