Event channel handlers cannot be removed during resume because there might be an interrupt thread running on a CPU currently blocked in the cpususpend_handler, which prevents the call to intr_remove_handler from finishing and completely freezes the system during resume. r291022 tried to fix this by allowing recursion in intr_remove_handler, but that's clearly not enough. Instead don't remove the handlers at the interrupt resume phase, and let each driver remove the handler by itself during resume. In order to do this, change the opaque event channel handler cookie to use the global interrupt vector instead of the event channel port. The event channel port cannot be used because after resume all event channels are reset, and the port numbers can change. Sponsored by: Citrix Systems R&D MFC after: 5 days |
