Hello, I cannot boot a powerbook g4 with kernels more recent than 3.16. Using 5.6 and 5.7 from sid, the system blocks after printing these lines:
pmac32_cpufreq: registering PowerMac CPU frequency driver pamc32_cpufreq: Low: 667 MHz, High: 867 Mhz, Boot: 667 MHz I opened a bug report (#963689) but I would like to contribute more information. How may I debug the problem? I tried a lot of kernel parameters without having any additional information on the screen. Would it be helpful to connect a serial cable (where?), use it to connect a console, and get more info? Is there any parameter that may be used for collecting more information when creating the initrd image? Thank you, Giuseppe
