There is one failing kernel selftest: global.user_notification_signal

Also - could you follow up with the author of this failing test to see if we can get some more clarity about what might be going wrong here? It appears that the failing test was added in commit 6a21cc50f0c7f ("seccomp: add a return code to trap to userspace") by Tycho Andersen tycho@tycho.ws.

Can you post an strace and a cat of /proc/$pid/stack for both tasks where it gets stuck? I don't have any riscv hardware, and it "works for me" on x86 and arm64 with 100 tries.

Thanks,

Tycho
