+Qemu ARMv7 TCG MultiThreading for i386 guest doesn't work
+
+Using any Linux image (in this case Alpine Linux iso) and want to use all cores of my Raspberry with --accel,thread=multi. I know there is a probably still problem with memory ordering of the host but I have also seen some very old commits which could potentially help with it.
+
+But anyway, with version qemu-i386 version 3.1.0 (Debian 1:3.1+dfsg-7)
+I can see OpenRC starting up services and then the kernel crash.
+
+With version QEMU emulator version 3.1.93 (v4.0.0-rc3-dirty)
+The whole machine crash with this error: 
+Illegal instruction
+
+
+Using command:
+./qemu-system-i386 -cdrom alpine.iso --accel tcg,thread=multi
+
+Full Console Output:
+qemu-system-i386: warning: Guest expects a stronger memory ordering than the host provides
+This may cause strange/hard to debug errors
+Illegal instruction
+
