Did this ever work before? AFAIK AIX was never really running on QEMU...
Hi, Thomas. Yes! Of course I had it working beautifully before, with only a minor issue executing a small number of XCOFF binaries, that is why I specified the QEMU version (2.11.2) AIX last worked with in the title of this bug.

Pretty cool, right?
Something changed after 2.11.2 that broke something in the tcg cpu execution emulation.
This is the error I get when I try to boot AIX in any QEMU version > 2.11.2:
ERROR:/home/kens/tmp/qemu/cpus.c:1727:qemu_tcg_cpu_thread_fn: assertion failed: (cpu->halted)
This is an automated cleanup. This bug report has been moved to QEMU's
new bug tracker on gitlab.com and thus gets marked as 'expired' now.
