Hi Adrian, I tried these on my Dual-processor PCI-X G5.
> https://cdimage.debian.org/cdimage/ports/tests/ppc64-test/debian-12.0.0-ppc64-NETINST-1.iso > https://cdimage.debian.org/cdimage/ports/tests/ppc64-test-new/debian-12.0.0-ppc64-NETINST-1.iso Both behaved the same way. Got to the installer menu, I choose an install mode, showed "loading..." for approximately 1 minute bit, then showed normal messages like 'Quiescing OpenFirmware...' and 'Booting Linux via __start()', and within 1 second Linux printed: smp_core99_probe smp_core99_kick_cpu smp_core99_kick_cpu_done smp_core99_bringup_done but after that nothing more. After 1-2 minutes the fans spun up fully. After 3-5 minute I gave up and held power button to power down. > https://cdimage.debian.org/cdimage/ports/snapshots/2024-02-25/ This one got to the four smp_core99_* messages, but the fans did not spin up. I waited 12 minutes but the screen did not update. Is there anything I can help to diagnose from my end? -Richard On Mon, Feb 26, 2024 at 2:10 AM John Paul Adrian Glaubitz < glaub...@physik.fu-berlin.de> wrote: > > Hello, > > I have done some debugging on ppc64 to find out why the the kernel no > longer boots on PowerPC G5 (PowerPC 970) systems. > > It turns out that the issue is much more complicated than I expected since > the same kernel that doesn't boot debian-installer boots perfectly fine > when installed after installation. > > I used QEMU for testing using the 970 CPU type (-cpu 970) and Mac99 machine > type (-M mac99).
