Page fault #1

Closed WinExperements closed 1 year ago

WinExperements commented 2 years ago

If you run the test program inside init program that runnned inside the init, then you got page fault. This issue is created by me, to not forget it. After debug, the issue is in memory manager that returns page that used as page directory for the init process, as result it's got modified.
