Dear Dell folks,


One of our systems is a Dell Inc. PowerEdge T630/0W9WXC, BIOS 2.1.5 
04/13/2016 with an Intel Haswell processor [1].

```

Although this is a server with ECC memory, which costs quite a lot of 
money, even with the latest Linux kernel, Linux 4.8-rc3, the EDAC driver 
does not support this chipset.

```
$ dmesg | grep -i edac
[    5.650704] EDAC MC: Ver: 3.0.0
$ sudo edac-util --status
edac-util: EDAC drivers loaded. No memory controllers found
```

That’s unacceptable for that kind of money that system costs.

My current suspicion is, that just a PCI ID is missing in the driver.

Dell might say, that it’s Intel’s job to adapt the Linux, but frankly, I 
do not care. Dell should make sure, that these things work out of the 
box, and it’s Dell’s job to verify that, and, if they can’t fix it, 
contact Intel to fix it.

Do I need to open a separate ticket for this issue, or are Dell 
employees reading this, who can bring it up with the right people?


Best regards,

Paul Menzel
