Issue

Under shared HA EDA workloads on Cloud Volumes ONTAP for Google Cloud, a timing-sensitive condition can cause an invalid memory access and a node reboot. The same failure signature has been observed on multiple nodes, including both nodes of an HA pair. The reported system message is {}PANIC: page fault (supervisor read data, page not present) on VA 0x28 in SK process mvrd_intr_handler{}. Repeated events may interrupt service during HA recovery; possible data corruption is also associated with this issue.
