[Qemu-discuss] qemu 1.3.0 hangs on macos 10.8.2

[cmason]

I'm trying to get qemu working on my Mac running 10.8.2 so I can cross
compile compilers and various other things for the raspberry pi.  I've
followed instructions:

http://www.rpiforum.net/forum/tutorials/article/16-a-raspberry-pi-emulated-environment-on-osx-lion/
http://igor.gold.ac.uk/~mas01mjy/wp/?p=95 
https://github.com/jeremyckahn/pine/wiki/Installing-QEMU-on-OS-X

I've tried both qemu 1.1.0 and 1.3.0 using homebrew.  I've also tried
manually compiling 1.3.0 with clang (default cc) and with gcc-4.2.  I've
used the configure options:

./configure --disable-sdl --disable-kvm --enable-cocoa --cc=gcc-4.2
--host-cc=gcc-4.2

(I've also tried with standard clang cc.)

All of these combinations simply result in an empty white window when
launching the raspbian wheezy 2012-12-16 image and a kernel I compiled
locally (which boots on the teensy) using:

qemu-system-arm -M versatilepb -cpu arm1176 -m 256 -hda
raspberry-qemu.ext4 -kernel zImage -append "root=/dev/sda2" -serial
stdio

Figuring it might be something with this raspberry pi kernel or image,
I've also tried the exact debian squeeze image, initrd, and vmlinuz this
page claims to have working:
http://psellos.com/2012/08/2012.08.qemu-arm-osx.html

This results in 

> qemu-system-arm -nographic -M versatilepb -kernel vmlinuz-2.6.32-5-versatile 
> -initrd initrd.img-2.6.32-5-versatile -hda 
> debian_squeeze_armel_standard.qcow2 -append "root=/dev/sda1 console=ttyAMA0"
Uncompressing Linux... done, booting the kernel.
[Hangs, basically indefinitely; I've waited hours.]

Since this supposedly works for others, it must have something to do
with my setup but I can't figure out what it is.  I've read about folks
with similar white screen hanging problems due to clang, but as said
above, I've tried with gcc-4.2, and with the 1.3.0, which indicates it
works with clang anyway.

Any help would be most appreciated.
