I have lost my sensors info with 2.6.10, in particular -mm1. They work fine with 2.6.9-mm1 (current state of the box, booted on 2.6.9 or 10, no other difference). Some info follows. With 2.6.9-mm1, I get this: Module Size Used by w83627hf 25128 0 i2c_sensor 3456 1 w83627hf i2c_isa 2304 0 i2c_i801 7820 0 i2c_dev 8192 0 i2c_core 19712 5 w83627hf,i2c_sensor,i2c_isa,i2c_i801,i2c_dev sensors: w83627thf-isa-0290 Adapter: ISA adapter VCore: +1.49 V (min = +1.93 V, max = +1.93 V) .. With 2.6.10-mm1: Module Size Used by w83627hf 24224 0 i2c_sensor 3968 1 w83627hf i2c_isa 2304 0 i2c_i801 9996 0 i2c_dev 8960 0 i2c_core 20992 5 w83627hf,i2c_sensor,i2c_isa,i2c_i801,i2c_dev sensors: No sensors found! I have noticed different contents in /sys: under 2.6.9: /sys/devices/platform/i2c-1: /sys/devices/platform/i2c-1/1-0290: /sys/devices/platform/i2c-1/1-0290/power: /sys/devices/platform/i2c-1/power: under 2.6.10: /sys/devices/platform/i2c-1: /sys/devices/platform/i2c-1/power: So some /sys nodes are missing !!!
