I see the bug on NUC10i7FNK with Kernel 5.4.0-54 (Ubuntu Server)
You can also fix this by adding the line blacklist tps6598x to /etc/modprobe.d/blacklist.conf.
I'm still seeing this on Linux 5.9.0-4-amd64 #1 SMP Debian 5.9.11-1 (2020-11-27) x86_64 GNU/Linux, I have the NUC10I5FNK.
AFAIK there is no patch for it yet.
EDIT: Forgot to add, you may also need to run sudo update-initramfs -u for the blacklist to be incorporated into the initramfs and take effect.
@crozone Nice and convenient solution. Thank you!
Just found this discussion, I'm seeing it today on a NUC10i7FNH with Ubuntu 20.04.1, kernel 5.4.0-58-generic.
What I find strange is that I've been using this NUC for about two weeks, and I could swear 'irq/65-i2c-INT3' never stood out in the process list before, the average load dropped below 1.0 when idle, while it's in the top 5 nearly all the time now and the load doesn't drop below about 1.1 - 1.2 (right now it says 1.25-1.26-1.20).
It remains the same after some attempts to roll back the changes I made today and reboots.
So thanks for this solution.
[Edit] - I hadn't hardly noticed the fan in my NUC running, but about a minute after stopping the driver the fan stopped. That's when I realized that it had been on all the time the last few days, while it was hardly ever on before. So I think it started when I last installed updates and got kernel 5.4.0.58.
Still seeing this on
- 5.8.0-34-generic #37~20.04.2-Ubuntu SMP Thu Dec 17 14:53:00 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
- NUC10i7FNH (manufacture date 2020-09-02)
Thanks @crozone for the blacklist suggestion :)
Does that depend on what is plugged into the USB ports?!
(I had the issue (yesterday) on a NUC 10 i7 — otherwise I'd never have landed on this thread — and I ran modprobe -r tps6598x but it's really not a great solution.)
Got this issue again with latest 22.04.1 update. modprobe -r tps6598x fixes it.
- Intel NUC 10 i7
- Linux nuc10 5.15.0-47-generic #51-Ubuntu
- Nothing plugged except power & wifi.
Didn't notice it with previous kernel versions. Fan started to get louder and htop shows load 1.00 when system is idle.
Same here; it seems there was a regression in kernel 5.15.x, and confirmed on a Intel Frost Canyon NUC 10 with Core i7. In my case I'm running Debian 11 (bullseye), kernel 5.15.53-1-pve, so this is upstream in the kernel, and not Ubuntu-specific.
The behavior is the same as before: load > 1.0 due to irq/65-i2c-INT3, even when not running anything. Using modprobe -r tps6598x fixes it (temporarily).
I installed PROXMOX "5.15.74-1-pve" on my NUC10I5FNK and the first thing I noticed is that the temperatures were much higher than with the latest Ubuntu Kernel. I looked at the process and indeed removing the PD module does fix it. Then I found this solution, it would have saved me almost an hour of research. Thank you very much for posting it.
puhhh unfortunately I've got no idea, but I'm running 20.04.1 LTS (Kernel 5.4.0-54) while updating it regularly.
