Hi Claudiu, thanks for the explanation! > E.g.: if you keep the ASPM policy to default and generate a link up/down > event that will not be seen by Linux. A subsequent lspci will trigger it. Well, 'lspci' does not trigger it (at least the busybox version I am using). But setting the policy to 'performance' does. Then, the 'link down' event gets recognized late. I'd think this also proves your theory? Happy hacking, Wolfram
