Problem: When Hardware IOMMU is on, megaraid_sas driver initialization fails in kdump kernel with LSI MegaRAID controller(device id-0x73). Actually this issue needs fix in firmware, but for firmware running in field, this driver fix is proposed to resolve the issue. At firmware initialization time, if firmware does not come to ready state, driver will reset the adapter and retry for firmware transition to ready state unconditionally(not only executed for kdump kernel).
