Hi, list
My x86 machine(linux4.19) sometimes hangs, suddenly not responding in any way to the mouse or the keyboard.
How can I investigate why it hung up? Is there extra information I can find for a clue? Is there anything less drastic than power-off to get some kind of action, if only some limited shell or just beeps, but might give a clue?
Thank you for your attention to this matter.
