Problem Description: Kernel 2.6.10 no longer detect CPU core voltage and Fan
speeds. Were working fine on 2.6.9

Steps to reproduce: Install Fedora Core 3 kernel 2.6.10 (any release) on Asus
PC-DL hardware. It has been reported also on VIA based systems (run a search for
sensors 2.6.10 on Google Web and Google Groups).

Please report the exact modules you have loaded.

Also, does this still happen on a 2.6.11-rc4 kernel?
Comment 2 Mauro M. 2005-02-17 14:31:04 UTC
On 2.6.9:

----------------

Is there an available patch to bring 2.6.10 i2c as 2.6.11-rc4? I am afraid I
cannot test the whole 2.6.11-rc4 yet.


Comment 4 Jean Delvare 2005-02-18 05:18:06 UTC
I suspect that you have PNP ACPI enabled in 2.6.10. See bug #4014, which is
unfortunately still opened.
