I have a problem w/ min/max limits in general since using the asb100 driver
instead of as99127f. It seems that the hyst/over values aren't retrieved
properly from my sensors.conf. E.g.
label temp1 "mb_temp"
set temp1_over 45
set temp1_hyst 40
mb_temp: +21?C (high = +0?C, hyst = +0?C)
Although it doesn't affect everything
label temp2 "cpu_temp"
set temp2_over 65
set temp2_hyst 60
cpu_temp: +46?C (high = +60?C, hyst = +65?C)
I seem to have the same problem w/ some of the voltage settings (not getting
the -5v & -12v max/min values)
label in5 "-12V"
compute in5 -@ * 3.97 , -@ / 3.97
set in5_max -12 * 0.90
set in5_min -12 * 1.10
I've attached the asb100-* extract from my sensors.conf file for reference.

It's a variable speed smartfan (runs between 1300 & 4800RPM). It seems to work
best with a divider of 4 and "compute fan1 @/2.12, 2*@".

See above for my limits problem. The 19C value is the same as reported by the
BIOS. It's only about 21 degC in here at the moment & I'm pretty sure my
large fan is blowing on the air temp sensor. On cutting the fan it rises in
to the low 20s.

Nothing logged, I'll enabled some of the CONFIG_I2C_DEBUG_* options when I
move from kernel 2.6.2-rc2 to rc3 to apply your
linux-2.6.2-rc3-i2c-w83l785ts-retries.diff patch.

Will apply that patch in a second...
