I was recently contacted by somebody wishing to run mono on an embedded
PPC board so have been doing some testing with meta-mono against Yocto
Poky/Jethro on qemuppc. builds and runs under emulation, successfully running three
simple tests I created to check console, Windows Forms and GTK support.

ref: https://github.com/DynamicDevices/mono-helloworld/tree/master/src and both build and successfully execute the console
and GTK tests but the Windows Forms test fails with:

unknown opcode atomic_add_i4 in mono_arch_output_basic_block()
* Assertion: should not be reached at mini-ppc.c:4507

The stack trace includes

  at <unknown> <0xffffffff>
  at System.Windows.Forms.KeyboardLayouts.LoadLayouts () <0x000a4>

Full trace is here:  http://pastebin.com/4bJ173Sa

Can anybody advise?
