Hi Karel, I just committed a fix that should stop these messages: > [29574470494,3] OPAL: Called with bad token 117 ! That probably doesn't fix things, but nevertheless it would be interesting to try a new snapshot in a day or two. Snapshots can be downloaded from: https://ftp.openbsd.org/pub/OpenBSD/snapshots/powerpc64/ At this point OpenBSD does not run under QEMU's PowerNV emulation. I don't understand why, but I see some meory corruption that doesn't happen on real hardware. It is actually possible to build powerpc64 kernels on (for example) an amd64 machine. If you install the llvm port: # pkg_add llvm And then build the kernel as follows: $ cd /usr/src/sys/arch/powerpc64/compile/GENERIC $ make obj $ make config $ make CC="/usr/local/bin/clang --target=powerpc64-openbsd" stripping the final bsd kernel will fail, but the unstripped bsd.gdb can be used. If you put the bsd.gdb kernel on an HTTP server, together with a file with something like: label OpenBSD kernel http://server/bsd.gdb initrd http://server/bsd.gdb in it, you should be able to boot the kernel by using the "Retreive config from URL" menu option in Petitboot. I can also provide pre-compiled kernels or images for you to test. Cheers, Mark
