A nonvolatile queue manager queues entries of host data from one or more host channels to one or more write buffers for storage in one or more nonvolatile memory devices of a nonvolatile memory array. The nonvolatile queue manager compares a number of the entries queued to one or more nonvolatile memory holdup power write thresholds based on detecting a power loss event. The nonvolatile queue manager tracks one or more locations in the nonvolatile memory array targeted by one or more of the entries extending beyond the one or more nonvolatile memory holdup power write thresholds. The nonvolatile queue manager initiates a mitigation action on a subsequent restoration of power to handle the one or more locations in the nonvolatile memory array targeted by one or more of the entries extending beyond the one or more nonvolatile memory holdup power write thresholds.
