We can involve ODM's BIOS/EC team if it's necessary. (In reply to Kai-Heng Feng from comment #0) > When I plug/unplug Dell Dock WD19TB into Latitude 9510 in S2idle, the system > doesn't wakeup.

My statement is wrong. acpi_ec_dispatch_gpe() return true only if there is some GPE other than EC fired, There is a thread to track this, but unfortunately I didn't get any update from it. Are we still going to track this? I guess we can close this. Without ODM's cooperation we can't do much. |
