Something about the way > systemd-coredump handles coredumps is not compatible with > wait_event_killable. This is my experience too that systemd-coredump is doing something unexpected. When I tested the patch: https://lore.kernel.org/lkml/cover.1629655338.git.olivier@xxxxxxxxxxxxxx/ to make sure that the patch worked, sending coredumps to systemd- coredump was making systemd-coredump, well, core dump... Not very useful... Sending the dumps through a pipe to anything else than systemd-coredump was working fine.
