If so, this is > regression. That is difficult as 5.13.0 has the line: OF: fdt: Reserved memory: failed to reserve memory for node 'secmon@5000000': base 0x0000000005000000, size 3 MiB But doesn't crash. It could be that no process used that address so no crash. > > Thanks. > > -- > An old man doll... just what I always wanted! - Clara _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
