A bus fatal error was detected on a component at bus 0 device 7 function 0

Hi all,

I'm trying to diagnose a hardware issue with my Dell PowerEdge R410. The issue occurred after doing a linux kernel security patch and restarting (I'm running Ubuntu 14.04 and am on Linux 3.13.0-100-generic). Initially, the machine would crash while booting into the OS but I somehow managed to get it too boot up consistently.

I'm seeing the following errors:

--------------------------------------------------

Severity : Critical
Date and Time : Sat Oct 22 05:50:30 2016
Description : A bus fatal error was detected on a component at bus 0 device 7 function 0.

Severity : Critical
Date and Time : Sat Oct 22 05:50:30 2016
Description : A bus fatal error was detected on a component at slot 1.

I'm having a hard time figuring out which component this refers to exactly. Here is the lspci output:

------------------------------------------------------------------------------------------------

So one of the components appears to be "00:07.0 PCI bridge: Intel Corporation 5520/5500/X58 I/O Hub PCI Express Root Port 7 (rev 13)", but I'm unclear as to what this component is
and what it connects too. Also slot in, "A bus fatal error was detected on a component at slot 1." seems vague. What is slot 1 in this case?

My specific questions are:

Which components do the critical errors apply to?

Should I do things in the following order:

- Unplug power cord and hold power button for 20 seconds
- Firmware updates
- Try reseating components
- Replace parts

PS. I'm no longer under warranty

Thanks,

Dave
