Hello, I'm seeing crashes with 4.0.1 in notify_via_xen_event_channel() after evtchn_destroy() was already executed, the ASSERT triggers. There are a few calls to notify_via_xen_event_channel(), only hvm_send_assist_req() seems to check the domain->is_shutting_down flag. xen-unstable is not much different in that area. How should a check for an already destroyed eventchannel look like? Maybe like its done in free_xen_event_channel()?
