Ever since i have updated my supermicro motherboard BIOS i have been receiving these errors in the system log.

 

Feb  1 15:47:48 Tower kernel: pcieport 0000:00:1c.0: AER: Corrected error received: id=00e0
Feb  1 15:47:48 Tower kernel: pcieport 0000:00:1c.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=00e0(Transmitter ID)
Feb  1 15:47:48 Tower kernel: pcieport 0000:00:1c.0:   device [8086:a110] error status/mask=00003000/00002000
Feb  1 15:47:48 Tower kernel: pcieport 0000:00:1c.0:    [12] Replay Timer Timeout  

 

After BIOS flash i have cleared CMOS and set up the server as "i think" i had it prior to the update.

 

8086:a110 is

8086:a110] 00:1c.0 PCI bridge: Intel Corporation Sunrise Point-H PCI Express Root Port #1 (rev f1)

 

Would appreciate any input many thanks

Those can sometimes be fixed by using the offending controller on a different PCIe slot (ideally changing from a CPU slot to a PCH slot or vice versa) or with a bios update.

thanks i was getting a bit worried as i thought the error was spamming the logs when i booted the server up, but that is not the case and the errors have not returned.

Quick follow up about this because its been bugging me since i flashed the BIOS. When i revisited supermicro i found only an older BIOS which once flashed has been fine and i have no syslog errors now.

I reached out to supermicro for an answer, they said.

 

"The BIOS 2.2 we had on our website had fixes for the Spectre vulnerabilities.
However, the fixes had issues and Intel has asked all Vendors to revoke the updates until new Micro codes can be released.

So it's possible the new BIOS had the issues you saw, and our current advise would be to use the 2.0c BIOS version from our website."

 

 

Yeah, I already noticed they had removed the latest bios for most boards, unfortunately only after I already updated all three X11SSM-F I have, still they are working fine so far so I'll wait for a new bios instead of downgrading.

I have updated the newer 2.2b BIOS.

 

The same errors started to spam the log file continuously again. It is occupied by my RocketRAID 640L. Before i decided to occupy the only other PCIE slot (x16) i read THIS bug report thread which has a few fixes to try.

 

I have turned off/disabled pcie aspm on the x4 currently used slot.

 

This power management option has fixed this issue. No more error logs.

may i know which power management option? because i think i am experiencing similar issues. 

This also worked for me with a PCIe x4 NIC on the CPU slot in my ASUS board (both my PCH slots are full).  Turned off all ASPM options for PCIe in the BIOS and the log errors went away.
