The original and easily observable bug is that were are not generating symbol checksums for the asm-exported symbols, so they default to 0. This can be seen e.g. in the Module.symvers file. This seemed like a minor issue, because with the functions written in asm, the type checking is rather weak (this has been the case even before Al's patches). However, there is another bug that with _some_ toolchains / architectures, the checksums do not default to 0, but they are simply missing in the ___kcrctab* sections and the module loader complains. We can of course research into the details of the second bug, but we already know that we are not generating the checksums while we should be.
