We've seen occasional issues where linux-yocto:do_compile_kernelmodules would run without do_shared_workdir running before it. do_shared_workdir is an setscene task but never has an sstate object generated so it will always rerun. This should not happen since compile_kernemodules should only execute if a setscene that depends on it didn't run and that should trigger do_shared_workdir not to be marked as covered. The issue is that build-appliance-image:do_package is one of the tasks which covers linux-yocto:do_compile_kernelmodules but it is also a noexec task and has a dependecy on pseudo-native:do_populate_sysroot. In the problem case, pseudo-native:do_populate_sysroot is unavailable but marked as covered since it is noexec. The "harddeps" code then also marks it as notcovered. No task should ever be both covered and notcovered and this is where the problems come from. The solution is for the harddeps code only to to fail tasks if they've not already been handled in some way. The code is assuming code couldn't have handled revdeps at this point but we now have clear evidence they can.

Bitbake
BitBake is a generic task execution engine that allows shell and Python tasks to be run efficiently and in parallel while working within complex inter-task dependency constraints. One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software stacks using a task-oriented approach.
For information about Bitbake, see the OpenEmbedded website: http://www.openembedded.org/
Bitbake plain documentation can be found under the doc directory or its integrated html version at the Yocto Project website: http://yoctoproject.org/documentation
Contributing
Please refer to http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded for guidelines on how to submit patches, just note that the latter documentation is intended for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org) but in general main guidelines apply. Once the commit(s) have been created, the way to send the patch is through git-send-email. For example, to send the last commit (HEAD) on current branch, type:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org
