Hi Barton,

> The script wants these modules loaded:
> MODULE_0=i2c-matroxfb
> MODULE_1=i2c-isa
> MODULE_2=ddcmon
> MODULE_3=w83627hf
> i2c-matroxfb is uneeded and creates the problem with the smbus and

The ddcmon driver is a Linux 2.4-only driver, which is now deprecated in
favor of the more standard eeprom driver with a userspace decoding
script. More recent versions of the sensors-detect script would suggest
the eeprom driver in this case.

I would tend to agree with you that loading the i2c-matroxfb driver by
default is not a good idea, as this will first load the matroxfb driver
itself, which may cause problems as you experienced. Not everyone wants
a framebuffer console. Ideally, we would only load i2c-matroxfb if
matroxfb itself is already loaded. I have no immediate idea how this can
be done though.

Thanks for the report anyway.
Jean Delvare
