There seems to be a regression in the kernel which affects PowerPC 970 machines,
i.e. PowerMac G5 CPUs. The issue needs to be bisected and reported upstream.

If you have the time, I would really appreciate if you could test the various
snapshots and let me know which kernel is the first to not work. I expect that
the breakage occurred somewhere around kernel 6.3 or so.

CC'ing Claudia Neumann who observed this bug before and can maybe share some
additional information.
