scsi4 : qla2xxx
kernel unaligned access to 0xe0000030066d000c, ip=0xa0000001005cd0b1

0xa0000001005cd0b1 is qla2x00_init_host_attr+0x71.

void
qla2x00_init_host_attr(scsi_qla_host_t *ha)
{
        fc_host_node_name(ha->host) =
            be64_to_cpu(*(uint64_t *)ha->init_cb->node_name);
        fc_host_port_name(ha->host) =
            be64_to_cpu(*(uint64_t *)ha->init_cb->port_name);
}

It looks like ha->init_cb->port_name.
