No, this is a custom kernel .config for my Talos II where it works fine. But next time I'll come up with a config which boots up in qemu too. ;) > FWIW, I see the config has the experimental > CONFIG_PPC64_BIG_ENDIAN_ELF_ABI_V2 set. Yes. I've been using this since available on kernel 6.2-rc1 on my PowerMac G5 and on the Talos II but with no (?) problems seen so far. Regards, Erhard
