Furthermore I've built (again the very same source) in groovy as 5.2+dfsg-9ubuntu2~groovyppa1 in the same PPA. This build works as well in my tries.
So I have the same code as in "1:5.2+dfsg-9ubuntu1" three times now: 1. [1] => built 2021-03-23 in Hirsute => works 2. [2] => built 2021-04-12 in Hirsute => fails 3. [3] => built 2021-04-13 in Groovy => works [1]: https://launchpad.net/ubuntu/+source/qemu/1:5.2+dfsg-9ubuntu1/+build/21196422 [2]: https://launchpad.net/~paelzer/+archive/ubuntu/lp-1921664-testbuilds-rebuildold/+build/21392458 [3]: https://launchpad.net/~paelzer/+archive/ubuntu/lp-1921664-testbuilds-rebuildold/+build/21394457 With the two results above, I expected as next step could spin up a (git based) Groovy and a Hirsute build environment. I'd do a build from git (and optimize a bit for build speed). If these builds confirm the above results of [2] and [3] then I should be able to upgrade the components in the Groovy build environment one by one to Hirsute To identify which one is causing the breakage... But unfortunately I have to start to challenge the reproducibility and that is breaking the camels back here. Without that I can't go on well, and as sad (it is a real issue) as it is it is riscv64 emulation on an arm64 host really isn't the most common use case. So I'm unsure how much time I can spend on this. Maybe I have looked at this from the wrong angle, let me try something else before I give up ... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to binutils in Ubuntu. https://bugs.launchpad.net/bugs/1921664 Title: Coroutines are racy for risc64 emu on arm64 - crash on Assertion Status in QEMU: New Status in qemu package in Ubuntu: Confirmed Bug description: Note: this could as well be "riscv64 on arm64" for being slow@slow and affect other architectures as well. The following case triggers on a Raspberry Pi4 running with arm64 on Ubuntu 21.04 [1][2]. It might trigger on other environments as well, but that is what we have seen it so far. $ wget https://github.com/carlosedp/riscv-bringup/releases/download/v1.0/UbuntuFocal-riscv64-QemuVM.tar.gz $ tar xzf UbuntuFocal-riscv64-QemuVM.tar.gz $ ./run_riscvVM.sh (wait ~2 minutes) [ OK ] Reached target Local File Systems (Pre).

This is often, but not 100% reproducible and the cases differ slightly we see either of: - qemu-system-riscv64: ../../util/qemu-coroutine-lock.c:57: qemu_co_queue_wait_impl: Assertion `qemu_in_coroutine()' failed. - qemu-system-riscv64: ../../block/aio_task.c:64: aio_task_pool_wait_one: Assertion `qemu_coroutine_self() == pool->main_co' failed. Rebuilding working cases has shown to make them fail, as well as rebulding (or even reinstalling) bad cases has made them work. Also the same builds on different arm64 CPUs behave differently. TL;DR: The full list of conditions influencing good/bad case here are not yet known.
