I would like to help debug booting AIX with qemu-system-ppc.
Recent versions of AIX are destined to fail on qemu-system-ppc. You'll need qemu-system-ppc64 and the ppc64 OpenBIOS instead.
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) ====================================================
Welcome to AIX. boot image timestamp: 00:39 35/2D The current time and date: 01:10:58 04/25/2011 processor count: 1; memory size: 2047MB; kernel size:2293829 boot device: cd:\ppc\chrp\bootfile.exe [hangs here...]
I had a version of OpenBIOS on which AIX complains about the 750 and drops back to the prompt.
============ Environment ============
OpenBIOS: SVN snapshot as of 2011-04-25 QEMU: Git snapshot as of 2011-04-25 Host OS: GNU/Linux x86_64 Guest OS: AIX V6.1Cross-Compiler: powerpc-unknown-linux-gnu-gcc (GCC) 4.6.0
Please see the list archives for info an which ppc64 cross-compilers work and how to build.

Otherwise I don't spot anything unusual in here, a diff would've been more reader-friendly.

You mean, you built with a different config than the one you posted above??? Anyway, the below debug output is too much and non-telling.
R: 7fb5bc80 R: 7fb5bc24 R: 7fb5bba0 R: 7fb5bbd8
IDE - ob_ide_read_blocks: ob_ide_read_blocks 7fb9f0a8 block=0 n=1 IDE - ob_ide_read_sectors: ob_ide_read_sectors: block=0 sectors=1 IDE - ob_ide_atapi_drive_ready: ob_ide_atapi_drive_ready R>: 7fb5bbd8
[...]
Despite the large amounts of debug outputs you didn't mention your command line. A standard -nographic output with the default debug config options would be much more appreciated. As stated earlier elsewhere, SVN HEAD does not yet work for AIX; patches are needed for RTAS (and QEMU).
