[Qemu-devel] [Bug 1694998] [NEW] PPC: msgsnd instruction leads to assertion

[Kurban Mallachiev]

Public bug reported:

I tried to send doorbells (using msgsnd) between cores in guest OS. On QEMU 
v2.9.0 usage of msgsnd instruction leads to error:
ERROR: <...>/qemu-new/translate-common.c:34:tcg_handle_interrupt: assertion 
failed: (qemu_mutex_iothread_locked())


QEMU v2.8.0 works fine.

QEMU run options: qemu-system-ppc -serial stdio -M ppce500 -cpu e500mc
-smp 2 -m 512M -kernel pok.elf

pok.elf attached
