Ok, can you then at least tell us what the latest kernel you have used
that was OK was?
Just to try and narrow things down a bit.

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.
