However, when using QEMU, the emulator sometimes randomly **crashes or aborts** during boot or early execution. The crash is **inconsistent** — sometimes it runs, sometimes it fails immediately. QEMU fails with an **assertion failure** in `qemu_mutex_lock_iothread_impl` Steps to reproduce: Unfortunately, I do not know exactly what causes this issue. It may be specific to my system or configuration. 1. 2. Additional information: Qemu stdout: ``` ERROR:system/cpus.c:504:qemu_mutex_lock_iothread_impl: assertion failed: (!qemu_mutex_iothread_locked()) Bail out! ERROR:system/cpus.c:504:qemu_mutex_lock_iothread_impl: assertion failed: (!qemu_mutex_iothread_locked()) ./run: line 3: 3544 Aborted (core dumped) ``` Command line: ``` qemu-system-x86_64 -debugcon file:OxizeOS.log -drive file=output/OxizeOS.hdd,format=raw -serial stdio ```
