Bug:

  • Currently driver/disk uses BIOS int 0x13 for that kernel change processor from protected mode to real mode and back.
  • After the return PIT doesn't trigger IRQ0 interrupt for some reason.
  • Within process_create(....) process init stack starts with eflags=0, which in turns starts user application with IF=0
