Abstract

Systems and methods are provided for implementing improved root cause analysis ("RCA") -based node recovery. After instructing a node to enter a debug mode and based on a determination that an expected response timeout duration has elapsed, a controller instructs the node to enter a system management mode ("SMM"), and exposes a shared buffer to an SMM handler of the node. The shared buffer includes instructions for the SMM handler to set a trap flag in a saved state area of an operating system ("OS") of the node and to use a resume execution instruction after setting the trap flag. The trap flag causes the OS to transfer control of problematic code to a trap handler, which performs operations or calls a hypervisor for a virtual machine extension ("VMX") root mode depending on whether the problematic code execution occurs in a non-maskable interrupt ("NMI") handler.
