Hello, after having upgraded QEMU to the end-of-February release, the problem (still there) evolved. Now there is no more a "nevereding loop", but QEMU crashes on stratup with the above described startup command :
qemu-system-x86_64w.exe -hda debian.img -m 256 -net nic -net > tap,ifname=TAP32 -soundhw all -serial COM9 Now it's easy to give you the Windows dump, attached.

The host system is Windows 7 64bits. I'm excuting the following statment : qemu-system-x86_64w.exe -hda debian.img -m 256 -net nic -net tap,ifname=TAP32 -soundhw all -serial COM9 Qemu starts the emulated Debian and it runs correctly. If I try to send data from Windows using COM9 to QEMU (both "real" or emulated by the COM0COM driver), QEMU crashes. Windows dump available if required. If I try to send data to /dev/ttyS0 (that should be the Linux side of COM9) from Debian, again, the wirtual machine crashes. More details if necessary Best regards U.Poddine To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1423124/+subscriptions
