+description = """There is a `SIGUSR2` or `SIGUSR1` raised which causes QEMU to abort:
+```
+(lldb) bt
+* thread #3, stop reason = signal SIGUSR2
+  * frame #0: 0x0000000184c384a4 libsystem_kernel.dylib`__sigsuspend + 8
+    frame #1: 0x0000000100b7ff34 qemu-system-aarch64`qemu_coroutine_new at coroutine-sigaltstack.c:221:9

+
+I tried skipping over it with `lldb`:
+```
+(lldb) b main
+(lldb) r
+(lldb) process handle SIGUSR1 -s false -p true
+(lldb) process handle SIGUSR2 -s false -p true
+(lldb) c
+qemu-system-aarch64: Unknown Error
+```
+
+I investigated the Unknown Error and and it's actually `HV_ILLEGAL_GUEST_STATE` which is unhandled in the `assert_hvf_ok` function. From here the VM will fail."""
