Hi Rudolf,

Yes, I see from the k8temp.c
static SENSOR_DEVICE_ATTR_2(temp1_input, S_IRUGO, show_temp, NULL, 0, 0);
static SENSOR_DEVICE_ATTR_2(temp2_input, S_IRUGO, show_temp, NULL, 0, 1);
static SENSOR_DEVICE_ATTR_2(temp3_input, S_IRUGO, show_temp, NULL, 1, 0);
static SENSOR_DEVICE_ATTR_2(temp4_input, S_IRUGO, show_temp, NULL, 1, 1);

So,
temp1 == CPU#0 Core#0 Temp #0
temp2 == CPU#0 Core#0 Temp #1
temp3 == CPU#0 Core#1 Temp #0
temp4 == CPU#0 Core#1 Temp #1

My Dual Core Opteron (265) only reports temp1, and temp3.
That is OK. One temperature per core.

What would it look like if I add a second physical processor in
the second socket? Would I get the same lmsensor names repeated?

Here are the logs.
It looks like a timeout problem....
