Could not insert 'it87': Device or resource busy

[mariusmotea]

Hi,

Any idea why i cannot load this module? I tried both dkms and regular compilation methods and the result is the same. I get the ITE device address using sensors-detect

Found `ITE IT8686E Super IO Sensors'                        Success!
    (address 0xa40, driver `to-be-written')

root@pve:~/it87-master# modprobe it87 force_id=0xa40
modprobe: ERROR: could not insert 'it87': No such device

Thanks.

I bet there's no need for DKMS - my ITE IT8688E (on a Gigabyte Z390-UD) works with in-tree driver (Linux 4.18) nicely with force_id=0x8628

(You're supposed to enter chip ID, not its address)

It also works with other IDs, but doesn't expose as many sensors (the motherboard has 6 zones). One voltage sensor is showing 0V, but that's to be expected from using wrong driver ;)

You should try this ID and others, just like it's written in the README on the main page ;)

Thanks,

I tried also with the chip id but the issue in my case was solved by adding in grub config acpi_enforce_resources=lax.

Gigabyte Z390 UD. Ubuntu 18.04 kernel 4.15.0, lm-sensors 3.4.0. My workaround confirms described actions :
I have used acpi_enforce_resources=lax in /etc/default/grub
and after that sudo modprobe it87 force_id=0x8628
Sensors shows both my connected cpu fan and sysfan 1.

Yes, I used acpi_enforce_resources=lax already anyway, so I simply didn't think to document this here. Thanks.

And all 4 fan controllers on the Z390-UD work, saying this just in case someone in the future might misinterpret the above as only two of them working :)

same for me, modprobe it87 only worked with acpi_enforce_resources=lax on arch linux 5.4

I confirm that with that option I managed to make Gigabyte X570UD to start report fans speeds temperatures and voltages.
