acpi: spcr unexpected spcr access width. defaulting to byte size

Short question. 

I have UBUNTU 18.04 and 20.04 installed on a Dell R710.  I always get this message at startup, although it does not seem to affect the system at all:

acpi: spcr unexpected spcr access width. defaulting to byte size.

I found an article that says:

BIOS support for SPCR table:With the exception of thePowerEdge 1550, all fifth-generation and newer PowerEdgeservers support the Serial Port Console Redirection (SPCR)table. The SPCR table provides EMS with information aboutthe out-of-band management port as well as related configu-ration details. If the Dell PowerEdge server does not supportthe SPCR table, administrators must provide the EMS config-uration parameters and information about the out-of-bandmanagement port to the Windows Server 2003 OS by usingthe bootcfgcommand.3The same command may be used to change the default configuration of EMS even if the serversupports the SPCR table
