Recently it's reported that PowerPC macMini system failed to boot up. It's because CONFIG_CRASH_DUMP=y is set by default on the system since kernel 6.9, and that makes CONFIG_PHYSICAL_START not equaling 0 any more and causes failure of normal kernel bootup. The link of error report can be found here: https://lists.debian.org/debian-powerpc/2024/07/msg00001.html And copy the code snippet here for reference: arch/powerpc/Kconfig: ================== config KERNEL_START hex "Virtual address of kernel base" if KERNEL_START_BOOL default PAGE_OFFSET if PAGE_OFFSET_BOOL default "0xc2000000" if CRASH_DUMP && !NONSTATIC_KERNEL default "0xc0000000" So let's stop enabling CRASH_DUMP by default on PPC_BOOK3S_32.
