Hello, I would like to help debug booting AIX with qemu-system-ppc. Here is what I have so far, please let me know what further information I should provide to aid in pinpointing where the following hang occurs:
====================================================
Booting AIX in QEMU+OpenBIOS (CPU type PowerPC,750)
