Hello,

we recently bought a Dell poweredge R720 server. It shows error massege in the display. "cpu0000 cpu1 internal error (IERR) contact support "

What could be the reason? Hardware problem.

We are going to install Ubuntu 12.04 server on it.

Hi Liyanage,

As of Ubuntu, there is some bugs that need some fixes in the next update 12.10 for this issue.

But I can try to suggest to do 1 step for a try to fix issue.

You might need to turn off the C-State in the BIOS for the server. After booting into the BIOS, go to System Profile Settings > Set it to custom and disable to C-state.

1 more thing to do is to clear the hardware logs, and check if the issue can surface.

Let me know how it goes.

Dear Chong,
