When both EFI and memblock debugging is enabled on the kernel command line: 'efi=debug memblock=debug' .. the debug messages for early_con look the following way: [ 0.000000] efi: 0x0000e1050000-0x0000e105ffff [Memory Mapped I/O |RUN| | | | | | | | | | |UC] [ 0.000000] efi: 0x0000e1300000-0x0000e1300fff [Memory Mapped I/O |RUN| | | | | | | | | | |UC] [ 0.000000] efi: 0x0000e8200000-0x0000e827ffff [Memory Mapped I/O |RUN| | | | | | | | | | |UC] [ 0.000000] efi: 0x008000000000-0x008001e7ffff [Runtime Data |RUN| | | | | | | |WB|WT|WC|UC] [ 0.000000] memblock_add: [0x00008000000000-0x00008001e7ffff] flags 0x0 early_init_dt_add_memory_arch+0x54/0x5c [ 0.000000] * ... Note the misplaced '*' line, which happened because the memblock debug message was printed while the EFI debug message was still being constructed.. This patch fixes the output to be the expected: [ 0.000000] efi: 0x0000e1050000-0x0000e105ffff [Memory Mapped I/O |RUN| | | | | | | | | | |UC] [ 0.000000] efi: 0x0000e1300000-0x0000e1300fff [Memory Mapped I/O |RUN| | | | | | | | | | |UC] [ 0.000000] efi: 0x0000e8200000-0x0000e827ffff [Memory Mapped I/O |RUN| | | | | | | | | | |UC] [ 0.000000] efi: 0x008000000000-0x008001e7ffff [Runtime Data |RUN| | | | | | | |WB|WT|WC|UC]* [ 0.000000] memblock_add: [0x00008000000000-0x00008001e7ffff] flags 0x0 early_init_dt_add_memory_arch+0x54/0x5c ... Note how the '*' is now in the proper EFI debug message line.
