Occasionally I see the Intel x520 cause or be involved with a fatal PCIe error. Almost all the time the fatal error is seen while updating the NIC firmware or rebooting the server. This has happened across many different R620s and x520 NICs. It doesn't necessarily mean the NIC is bad as they run fine.
Anyone see this and/or know what is causing it?
Errors like this appear in the ESM log:
"A bus fatal error was detected on a component at bus 64 device 1 function 0"
"A bus fatal error was detected on a component at slot 1."
Thanks for any help.
