ACPI errors on Dell T40 with Centos 8.x

Hello secan,

I'm sorry to see you have ACPI error messages on CentOS 8. 

I'm not seeing that as a Dell validated OS. We only have validated:

Supported operating systems:  https://dell.to/34l0Obr

• Ubuntu® Server 18.04 LTS
• Windows Server 2016

That doesn't necessarily mean it won't work, just that we don't have support for that OS. 

You may disable the related option in the boot loader and check results.

Have you verified your firmware are up to date?  https://dell.to/34hSUzL

I hope this helps.

Hello, thanks for the fast response.

The BIOS firmware is up to date (1.3.1), other firmwares than BIOS, I don't think I can update (nothing on DELL's site). It's strange that the T40 is not RHEL supported (which is a server), but Precision 3630 is supported (which is a desktop), and practically the 2 are almost the same device. I could tweak the bootloader (toggling acpi=off or blacklisting acpi_power_meter), but I'm not sure how much it will impact performance and/or power consumption.

I don't know what "Region handler [WST1]" does it mean in ACPI context?

As an update:

I can confirm that the issue is present in Ubuntu 18.04 LTS too:

So, to sum it up, the same issue is present in Ubuntu 18.04 LTS (kernel 4.15.x), Centos/RHEL 8.x (kernel 4.18.x), Fedora 32 (kernel 5.6.x).

My guess is that it's an ACPI table issue from DELL, which could be fixed with a BIOS/UEFI update.

Any hints?

Hello secan,

Thank you for that update with Ubuntu 18.04.

Has hardware been added? Third party cards? Anything different than original configuration?

See if Disable USB wake support in the BIOS has any affect.

I'll have to do some more checking.

Hello secan,

Thank you for the update. What are the original third party cards?

See if this helps. This post shows very similar errors you have with resolution posted:
https://dell.to/327tBxq
Go into BIOS by booting with F2. From there, go to System Configuration / SATA Operation / Choose "AHCI" 

Hello,

AHCI is enabled (I don’t use RAID), no third-party cards (OEM/non-OEM), the behavior is the same. 

Hello,

Any progress regarding this issue?

Hello,

The system is booting fine (I may say), is just that the error is annoying every time the system boots up. I just want to be sure that there's not performance or power consumption impact. I'm also curious about WST1 Region handler, in terms as what it is? In this case I can investigate/troubleshoot further on my device, this way we may find the issue.

Hello,

I don't familiar with this warning. Honestly, I couldn't find out any known issue directly about it.  But the closest result I could find was an article for RHEL 7.5 for R430. And it says "Dell engineering is aware. BIOS and Kernel are being investigated. There is no loss of functionality seen. the problem seems to be a cosmetic issue and that issue is industry-wide and not limited to Dell." Is it informational alert or Is it stopping the system from booting? If the system does not boot normally I may recommend that call into support for a log review. 

Hello secan,

I shared this information with one my Linux peers. It appears that this is only an informational alert. 

If it is causing operational issues I'd recommend call in to Support for an engineer to review logs.

This issue is going to require more direct attention than what can really be provided in the forum.

Hi thanks for choosing Dell. Is the card plugged in the slot and the USB device from Dell, could you confirm?
