I have been tortured by a tiny bug for a long time. Now I really hope to fix it.

They only shows when I boot/turn off my computer, although it doesn't influence anything.

  • when I boot my pc, it usually shows:
/dev/nvme1n1p3: clean, **** files, **** blocks
[   5.004707] nvidia-gpu 0000:05:00.3: i2c timeout error e0000000
[   5.004734] ucsi_ccg 0-0008: i2c_transfer failed -110
[   5.004772] ucsi_ccg 0-0008: ucsi_ccg_init failed - -110
  • when I turn off:
[   42.056815] ata2: failed stop FIS RX (-16)
[   43.065169] ata1: failed stop FIS RX (-16)

My configuration: Win 10 Pro + Ubuntu 20.04, RTX 2060s, amd r7-3700x.

I just don't want to see them everytime when I turn on/off my pc! Is there anyone know how to fix this?

Much appreciate:)

  • Btw, I remember I edited some configuration related to nvidia when installed ubuntu 20.04, but I can't remember them now. I don't have the integrated graphics with this PC.

I also have this issue in my Windows 10 + Arch Linux. It seems to be a bug in nvidia driver, as discussed in this link. Some nvidia cards don't have USB Type-C interface, yet still try to load its i2c driver. Hopefully this problem will be fixed in the next version of the driver.

As far as I know, there are two solutions for this problem in the meantime:

  1. You may try to patch your linux kernel, see the link above. If I understand correctly, the patch downgrades level of the error.
  2. You may want to create a file /etc/modprobe.d/blacklist_i2c-nvidia-gpu.conf with these contents: blacklist i2c_nvidia_gpu. This file prevents loading the problematic driver.

Personally, I use method 2, since my card doesn't have USB-C interface.

    How did you do method 2? I ran sudo nautilus and pasted the .conf file I saved to my desktop directory to the /etc/modprobe.d/ directory. But it didn't work. May 26, 2021 at 18:05
  • @JulienShepherd do su and then echo "blacklist i2c_nvidia_gpu" > /etc/modprobe.d/blacklist_i2c-nvidia-gpu.conf
