Well, with a simple good/bad test case like you have, the obvious thing to do would be to find a resonably new kernel that's good and one that's bad and then do a git bisection search to find the exact commit that broke things for you. Short of that, narrowing it down to a released version, a -rc or -git snapshot is also good.
You could also start browsing through changelogs looking for changes to IPC and then try revert patches that look likely. But git bisect is probably a lot easier.
