Thanks for your reply > The dme1737 driver depends on i2c-core and hwmon-vid. My guess is one or both of those aren't loaded. Do 'depmod -a' and then 'modprobe dme1737 probe_all_addr=1' to load the driver an all the modules it depends upon. Note that for the driver to correctly work on a SN18000 board, you need to have the following patch applied (hence the probe_all_addr option): http://lists.lm-sensors.org/pipermail/lm-sensors/2008-April/022802.html ...juerg > Jaroslav > > > > _______________________________________________ > lm-sensors mailing list > lm-sensors at lm-sensors.org > http://lists.lm-sensors.org/mailman/listinfo/lm-sensors > -------------- next part -------------- An HTML attachment was scrubbed...
