Hi Adrian,
In order to be able to reproduce, I started all over again. Using the same CD (
https://cdimage.debian.org/cdimage/ports/snapshots/2023-06-18/debian-12.0.0-powerpc-NETINST-1.iso ), booted and performed the installation. Formatted all the partitions clean.
I skipped the mirror stage and stick to CD-only installation.
Came again to the point where powerpc-ieee1275 is being installed and the system hangs there, waiting for the process to finish.
Again, in the system console, I get this:
INFO: task grub-install:7444 blocked for more than 120 seconds.
Not tainted 6.3.0-1-powerpc #1 Debian 6.3.7-1
...
...
(call trace comes here)
Is it something about this particular iMac model? What can I do?
Regards,
