I'm still available to test patches :-) Didn't see anything on this list nor on LKML. In particular I'm having a problem where it looks as if vmlinux is sending a signal to its parent process on shutdown. I can reliably reproduce this, although not with anything very minimal. But if you run the libguestfs test suite like this you'll see it: make -C tests/regressions check TESTS=rhbz914931 The parent process (a C program which for unrelated reasons is called 'rhbz914931') receives a SIGTERM. I checked the siginfo struct for this signal, and it appears to come from the vmlinux main process, which should not be happening. So .. possibly there's something awry with how vmlinux delivers signals to its child processes on shutdown which is causing it both to miss out some children, and to kill other unrelated processes. Or maybe this is just a coincidence.
