r620: Bus fatal error
A bus fatal error was detected on a component at bus 0 device 1 function 0. A bus fatal error was detected on a component at bus 1 device 0 function 0. CPU 1 machine check error detected. CPU 2 machine check error detected. An OEM diagnostic event occurred.
A server has started giving errors like the ones above. From posts with other servers, they refer to PCIe lanes.
Is there any reference on what exactly is failing?

There isn't a PERC installed, nor any additional PCIe devices.

If you already updated firmwares and BIOS I think that issue comes from motherboard that could be faulty.

Hello,
this error is most likely related to PCIe devices. Try to check PCI card installed on your server, and also PERC controller.
I suggest you to update fw and reseat perc controller, and perform a full update of all BIOS and firmware of the server.
Please let us know how can we help you further.
Thanks
