I don't want to hijack the original thread, so I'm replying in a new one. My tegra track current, has been running 24/7 by building kernel/world and kde5 in a loop for a few years now. But I have never encountered the aforementioned lockup in native armv7. I have seen usermode mutex lockup in arm32 jail on aarch64, but only very rarely (once a month or so) and all my attempts to reproduce it in a more deterministic way have failed. Also, I don't think I've ever seen this with the debug version of libc. Unfortunately I also failed to reproduce given lockup using dlopen_test.c, neither on native armv7 or arm32 jail. Michal Meloun
