Thank you for taking the time to test it. On my machine (Ubuntu 22.04), with QEMU configuration options "--target-list=aarch64-softmmu --enable-debug", running the provided test case with "-icount shift=0,sleep=off" still makes QEMU hang forever on commit 9eb51530c12ae645b. The issue was initially reported by a colleague of mine so I was hoping it would be somehow reliably reproducible. But apparently it is not. I will try to find some time to investigate a bit more. Thank you, -- Florian
