Hi Cristian, Because ACPI is exposed and currently enabled by the BIOS/EFI layer, linux is trying to register and set up a handle against a Serial Port.
While I acknowledge that dmesg contains the word "error", that doesn't mean there is a systemic issue, or an issue that would affect your use of the Serial Port. It just means that the Server isn't capable of "putting the Serial-Port to sleep", which is largely the role of ACPI. Therefore: - Can you confirm if the Serial Port is going to be used? It's very rare that it is needed / used. - If so, have you tested it by either: - - Installing "screen" on Linux, to use the Serial-Port for connection to an outside-device ( e.g. a Network Switch with a Legacy Serial Port ) - - OR - - Enabling Console-Redirection in the BMC/iDRAC, to send the Server-Console the opposite way ( e.g. Control the Physical Console from an outside Client ) Recommendations: - If you do not plan to use the Serial Port, you could disable it in the BIOS, or perhaps via Lifecycle-Controller UI. - This would be a good security measure, if the Serial Port is not needed in production. - This may also remove the "errors" you see in dmesg, which I would consider "non-critical" - at a glance. Final Words: - If the Serial Port is needed in production, but fails to work... this can surely be investigated further ( ideally via a Support Ticket ) - If the Serial Port does work; I would move on to another challenge. There is little to be gained from trying to adapt this behavior. ;-P Regards, Nick -----Original Message----- From: Linux-PowerEdge <[email protected]> On Behalf Of Secan Cristian Sent: 07 September 2020 15:04 To: [email protected] Subject: [Linux-PowerEdge] ACPI Error on Dell PowerEdge T40 [EXTERNAL EMAIL] Hello, I have a DELL PowerEdge T40 server.
