5.7. Common Issues with Kernel Modules

Try these first

1. 1.

   What command should you use to load a kernel module with its dependencies?

   Hint

   Think about a command that automatically handles dependencies.

2. 2.

   What does the command dmesg do?

   Consider which command automatically manages dependencies.

4. 4.

   True or False: Memory management is not critical for kernel modules.

   • True
   • False

   Hint

   Remember why efficient memory usage is necessary in kernel space.

5. 5.

   Hint

   Identify which module is causing the issue by reviewing the kernel messages.

6. 6.

   Explain the potential consequences of failing to manage memory correctly in a kernel module.

   Hint
