ACPI dump for Dell PowerEdge T40
Hello all,
As suggested by Zhang Rui from Intel, I've opened a new bug report related to
the exact same ACPI related issue encountered on Dell Precision 3630, the only
difference is that I have a slightly different model Dell PowerEdge T40.
Every time my system boots up, I receive the following ACPI error (early boot):

I can confirm that this issue is encountered on all Linux distros that I have
installed, regarding which flavour or kernel verion (be it 3.10 / 4.16 / 4.18 /
5.11 or 5.12).
As requested by Zhang, I've done the following troubleshooting steps:

As you can see, INT34B2:0 is not present at all.
3. The is no "ACPI enumeration mode" nor "PCI enumeration mode" present in the
BIOS system.
If there's anything else you need, please do not hesitate to reply.

Cristian
