Hello, I am still investigating the problem about kernel not booting on powerbook. I compiled many kernel versions and found the problem starts with 5.6 since 5.4.50 boots correctly.
Now, I would like to better follow the boot process, looking for what is done after the cpufreq driver setup. I cannot use the netconsole since the ethernet driver is not yet loaded when the boot process hangs. I already created a .config that include only a reduced set of kernel parts, but it is still quite large, of course. I would like to start knowing what is called after the cpufreq. How do I find it? I know that drivers/cpufreq/pmac32-cpufreq.c has an __init marked function and it is not compiled as a module. I understood that such marked function will be discarded once boot is complete, but I suspect somewhere a part of the kernel load all __init marked functions. Is this correct? Where is it? Thank you, Giuseppe
