Linux Kernel deadlock, Linux Kernel A deadlock is a state where multiple processes (threads) are blocked because they wait for resources occupied by other processes for a long time. When the waiting resources are not released, the deadlock will continue. Once a deadlock occurs, the program itself cannot be solved. It

Here we use the pico text editor. Run the "pico/etc/lilo. conf" command to start the pico editor and load the LILO configuration file.
