From fae21608c31ca987d9dfc0422ac9b5bd21c213a6 Mon Sep 17 00:00:00 2001 From: Sreekanth Reddy Date: Mon, 5 Jul 2021 20:29:50 +0530 Subject: scsi: mpt3sas: Transition IOC to Ready state during shutdown The IOC firmware assumes that the host driver is still alive after shutdown and continues to post events to host memory (due to faulty expander phy links, etc). This leads to 0x2666 (a bus fault occurred during a host-IOC memory access). Perform an IOC soft reset as part of shutdown to disable event posting.
