I test the qemu build like this,

qemu-system-m68k -M q800 -m 512M -serial none -serial mon:stdio -g 800x600x= 4
-net nic,model=3Ddp83932,addr=3D00:00:00:01:02:03
-net bridge,helper=3D/opt/qemu/libexec/qemu-bridge-helper,br=3Dbr0
-append "fbcon=3Dfont:ProFont6x11 console=3Dtty0 console=3DttyS0 ignor= e_loglevel"
-kernel vmlinux-4.14.157-mac-backport+
-initrd /mnt/loop/install/cdrom/initrd.gz

You can obtain this kernel binary from the linux-mac68k project on
sourceforge. (I usually use a mainline Linux build but it makes no
difference.)

I normally use a disk image with Debian/m68k SID rootfs but in this
example I've used the initrd that you can find on the Debian/m68k
installer ISO.

Once the guest starts, switch to a different virtual console and bring up <= br> the SONIC:

<ctrl>-<a> <ctrl>-<a> <2>
# ip addr add dev eth0 192.168.65.2/24
# ip link set dev eth0 up

On the host, send a ping flood (with preload) to the guest:

# ifconfig br0 192.168= .65.1/24
# ping 192.168.65.2 -f -l 20

The packet reception ("deaf sonic") issue is reproduced immediate= ly.

This has been observed in both qemu-m68k and mainline qemu. See also,

Finn,

I appreciat= e your detailed response!

Herve,
<= br>
Is there any way for us to come up with an equivalent or at l= east approximate scenario for Jazz machines?
