A bus fatal error was detected on a component at bus 64 device 3 function 0.

Hello TeslaTec,

 

Has any hardware been added or removed, or firmware updated, when this occurred?

In the iDRAC where you see the bus fatal error; Is there an entry near it that indicates a slot number?

 

 

Initial troubleshooting steps I can recommend:

*Flea power drain, test results

*Clear NVRAM, test results

*Minimum to POST configuration testing

 

 

drain flea power (shut down, disconnect power cables and Network cables, hold in power button 20 seconds with cords removed).  After flea power drain, system has to set for 3 minutes for DRAC to reset without any power plugged in, then plug in NIC and power but wait 2 minutes before power on to give DRAC time to initialize.

 

Clear NVRAM - there is a map under the lid to show the jumper location. Shut down,  Set jumper to the Clear position, power on and Post up to the jumper error, shut down and return to original location.

 

 

Minimum to post  (this is minimum components to POST, it won't boot, this is to test POST. If successful POST, put things back a little at a time until find faulting component)

 

The minimum components to allow the Dell PowerEdge R520 to complete POST are as follows:

 

*System Board

*CPU1 with heat sink (if no POST try with other CPU in CPU1 socket)

*Single DIMM configuration with DIMM in socket A1 (if no POST try a different DIMM in A1)

*Control Panel with cable

*Expansion Riser

*PSU (and for redundant PSU also the PDB/PIB)

 

Remove anything not on that list: DVD, Hard drives, PERC controller, backplane, network card, NIC cable, any pcie cards, keyboard, mouse, USB devices, ….  anything not on the list remove.

 

If it does not post then the issue is with one of those components.

If you get successful POST, put things back a little at a time until you find the faulting component.

 

 

When you can get into the function keys try run diagnostics and Update iDRAC and BIOS firmware:

 

Firmware  update:

IDRAC version: 2.60.60.60  (should be iDRAC: 2.65.65.65), Bios version: 2.1.2 (should be BIOS: 2.9.0)

When you can try to update the them : https://dell.to/3uT5HF8

 

 

For BIOS recommend to step up to BIOS 2.9.0 https://dell.to/3uRVSYa
