Hi, This is actually a continuation of [1] with more findings. The machine in question is a CFL desktop. The auto resume roughly happens in 5 ~ 10 mins. After further digging, I found out that the e1000e and XHCI always shares the same wakeup count in /sys/kernel/debug/wakeup_sources, so I did some experiment on e1000e. Here’s the tricky finding, disable WoL for e1000e can stop the erratic behaviour - the machine no longer auto resume. One caveat though - I can no longer wake up the system by pressing the BT keyboard. No idea where to file the bug so include all three subsystems.
