Start9 is synchronizing Bitcoin over a network chip that self-corrects every second

StartOS Support

Since replacing the Ethernet cable, the Start9 node continues to log multiple corrected PCIe receiver errors every second:

Kernel Log:
2025-12-09T20:45:33-03:00 pcieport 0000:00:1d.0: AER: Multiple Corrected error received: 0000:02:00.0
2025-12-09T20:45:33-03:00 r8169 0000:02:00.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)
2025-12-09T20:45:33-03:00 r8169 0000:02:00.0: device [10ec:8136] error status/mask=00000001/00006000
2025-12-09T20:45:33-03:00 r8169 0000:02:00.0: [ 0] RxErr (First)

No packet loss and link remains up, but log is flooded every second.
No performance degradation observed; Bitcoin Core continues syncing normally.

Actions Taken:
I replaced Ethernet cable but no change

I seeked the driver installed by Start9 and isn´t the official one:
lsmod | grep -E “r816|realtek”
snd_hda_codec_realtek 172032 1
snd_hda_codec_generic 98304 1 snd_hda_codec_realtek
snd_hda_codec 184320 6 snd_hda_codec_generic,snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec_realtek,snd_soc_hdac_hda,snd_sof_intel_hda
snd_hda_core 122880 9 snd_hda_codec_generic,snd_hda_codec_hdmi,snd_hda_intel,snd_hda_ext_core,snd_hda_codec,snd_hda_codec_realtek,snd_sof_intel_hda_common,snd_soc_hdac_hda,snd_sof_intel_hda

r8169 94208 0
realtek 36864 1
mdio_devres 16384 1 r8169
libphy 180224 3 r8169,mdio_devres,realtek

Confirm if this corrected-error flood is expected behavior for r8169 under continuous load, or please, provide steps to reduce or eliminate the log noise without affecting Bitcoin Core operation.

Thank you.

Can you please provide some context? What hardware are you running StartOS on? What was the first sign of trouble that caused you to replace the ethernet cable? What other additional information can you provide around the circumstances of this issue?

Hi Rexter,

Thanks for your response.

I installed the software on a laptop with the following specifications:

  • Architecture: x86-64

  • Hardware Vendor: Dell Inc.

  • Hardware Model: Inspiron 3593

  • Firmware Version: 1.30.0

I then installed Bitcoin Core, along with Electrs and Mempool, once the entire blockchain had been downloaded.

After that, I started monitoring the logs and found the issue I mentioned at the beginning in the kernel log.

I then decided to change the patch cable and try another plug on the home modem-router, but the log continues as usual—no change.

I think something is not fully compatible with the NIC controller. Perhaps we can slow down the connection to 100 Mb? Or is it possible to install this driver: r8168-dkms? I think it is more appropriate.

Which ISO did you use? For something with a realtek nic you’re going to need the x86_64-nonfree.iso because it includes such closed-source drivers.

Oh George, you’re absolutely right — I downloaded the wrong ISO file: startos-0.3.5.1-39de098_x86_64.iso.
Does that mean I have to start the installation from scratch, or is there another option?

You can choose “reinstall.”

Take a look at step 4.

Hi Rexter,

Thank you very much — I truly appreciate your answer. I’ve just downloaded the correct ISO file and I’ll follow your recommendation.
Thanks again!
