Thanks for the input James.
That does seem a similar problem, but it's specific to those Intel chipsets,
but the looks. The SC1435s we're I'm seeing the problem are AMDs.
Another interesting datapoint I've discovered is that the versions of
OpenIPMI only changed at the release level:
CentOS 4.4: 1.4.14-1.4E.13
CentOS 4.5: 1.4.14-1.4E.17
so I'm starting to wonder if it's perhaps a kernel change.
In addition, I've now verified that the sensors are behaving similarly
on CentOS 5.
Any other suggestions?
Cheers,
Gavin
