Additional info:

Please refer to bug 446061: https://bugzilla.redhat.com/show_bug.cgi?id=446061

This issue is fixed in later releases of lm_sensors. For example,
lm_sensors-2.10.3-2 from Fedora Core 7 works as expected.

I am happy to test any fix offered.
Comment 1 Niels de Vos 2008-12-05 07:18:04 EST
Same problem here with a it8718F-chip on CentOS-5.2. The feature request on the CentOS-bugtracker contains updated patches and spec for lm_sensors-2.10.7.
Comment 2 Phil Knirsch 2008-12-19 10:23:21 EST
Proposing for RHEL-5.4.

Thanks & regards, Phil
Comment 3 Phil Perry 2008-12-19 11:13:47 EST
Unless I'm mistaken, the version of lm_sensors proposed for RHEL-5.3 should fix this bug (requires lm_sensors >= 2.10.2). It is BugID 446061 that needs some movement. I have tested the supplied patch for 6 months and provided feedback yet there's still no sign of moving this forward towards release (it's still not fixed in the RHEL-5.3 beta kernels).
