WORKER_THREAD_RETURNED_WITH_BAD_PAGING_IO_PRIORITY
WORKER_THREAD_RETURNED_WITH_BAD_PAGING_IO_PRIORITY is the paging-I/O-priority counterpart to bug check 0x128. Microsoft states that the called worker routine wrongly modified the worker thread's paging I/O priority. The distinction is important: this code is not reporting the general I/O-priority field used by 0x128.
Map the failure to one worker routine
Parameter 1 is the worker-routine address and should be resolved with ln. Parameter 2 contains the current paging I/O-priority value. Parameters 3 and 4 identify the work-item parameter and the work-item object.
Review state restoration
Trace all returns from the routine named by parameter 1, especially exceptional, timeout, and cancellation branches. Any code that changes paging I/O priority must leave the shared system worker thread in the expected state before returning. Requeueing the work item or changing storage hardware does not fix leaked thread state.
