After certain amount of time (and workload), ioctls are hanging, rendering the box almost unresponsive to some operations. ddb showed that there are two suspects: mrsas_ocr_thread() nvme_ctrlr_passthrough_cmd() the rest of processes and threads are in sched_switch() OCR is Online Controller Reset. --=20 You are receiving this mail because: You are the assignee for the bug.=
