Hi folks, In BmDriverHealth.c, function BmRepairAllControllers may recursively call itself if some driver health protocol returns EfiDriverHealthStatusReconnectRequired. However, if there is something wrong in some 3rd party driver (e.g. PCI oprom), the driver health protocol of that driver may always return such status even after one and another reconnect. The endless iteration will cause stack overflow and then system exception, and it may be not easy to find that the exception is actually caused by stack overflow.
So does it make sense to set a maximum count of this recursive call to avoid whole system hang even there is a buggy 3rd party driver?
