Are you asking about the enumeration following link up while keeping the current code as is? Issue is observing hotplug link down event in the middle of AER recovery as in my previous reply. If we mask hotplug interrupts before secondary bus reset via my patch, then hotplug driver will not observe both link up and link down interrupts. If we don't mask hotplug interrupts, we have a race condition. I hope I answered your question. -- Sinan Kaya Qualcomm Datacenter Technologies, Inc. as an affiliate of Qualcomm Technologies, Inc.
