Hi,
I want to know how the kernel switch the task. Because my kernel
start very well, and it launch the init.d. With the log, i can see that
the kernel launch the getty task. But after, there is a decrementer
overflow interrupt ( vector at adress 900 ). Is it the task switch? Or
is it an error in the decrementer init.

This should be a task switch. The decrementer is used to handle the
periodic interrupt to switch processes.

I would have expected quite of few of these actually before you get
there :-)
