I have no rule about mouse or keyboard in my aml code.

Hi!

  
To SCI handler itself,  I don't think keyboard controller will be touched. But SCI handler could evaluate some AML method which could touch keyboard controller. --Luming

    

Would that be a bug in AML method? Or how is keyboard-controller
access locked between OS and ACPI?

   Does it mean the overhead of SCI interrupt was not the root cause of
   this issue. --Luming
      
It certainly looks so. Is it possible that SCI handler touches
keyboard controller?
