I was pleased to hear many thought in active developer's mind. I want to check some in MCA recovery. Here is some steps, roughly say: - Stop whole system on MCA even if kernel not suffered. - Keep working except the suffered application. - Keep working, and give a chance to self-rehabilitation for the suffered application. Just now, Linux is making an effort to step up the second from the first. It also seems there are some key procedures, such as: - Specify process/thread(s) must be killed - Specify damaged resources (for example, poisoned pages) To specify affected ones, OS requires: - Physical address (and if possible, Virtual address) of the offending operation. - Interruption must be synchronized. - States in registers when interrupted. Is it wrong? ------ H.Seto
