So, the original email says the riscv series is tested on top of 5.2-rc7, but just for fun, can you confirm that you're building a tree that includes 9dd3fcb0ab73 ("selftests/seccomp: Handle namespace failures gracefully")? I assume it does, but I suspect something similar is happening, where the environment is slightly different than expected and the test stalls. Does it behave the same way under emulation (i.e. can I hope to reproduce this myself?) -- Kees Cook
