Did this work on any other version of udev? What does 'tree /sys/class/i2c-dev' show?
although not sure 100% i believe it has worked before as expected (that is, sensors-detect script worked, which depend on /dev/i2c entries) /sys/class/i2c-dev is empty, although /sys/bus/i2c tree follows: /sys/bus/i2c/drivers /sys/bus/i2c/drivers/eeprom /sys/bus/i2c/drivers/eeprom/bind /sys/bus/i2c/drivers/eeprom/unbind /sys/bus/i2c/drivers/eeprom/module /sys/bus/i2c/drivers/dev_driver /sys/bus/i2c/drivers/dev_driver/bind /sys/bus/i2c/drivers/dev_driver/unbind /sys/bus/i2c/drivers/dev_driver/module /sys/bus/i2c/drivers/lm78-isa /sys/bus/i2c/drivers/lm78-isa/9191-0290 /sys/bus/i2c/drivers/lm78-isa/bind /sys/bus/i2c/drivers/lm78-isa/unbind /sys/bus/i2c/drivers/lm78-isa/module /sys/bus/i2c/drivers/lm78 /sys/bus/i2c/drivers/lm78/bind /sys/bus/i2c/drivers/lm78/unbind /sys/bus/i2c/drivers/lm78/module /sys/bus/i2c/drivers/i2c_adapter /sys/bus/i2c/drivers/i2c_adapter/bind /sys/bus/i2c/drivers/i2c_adapter/unbind /sys/bus/i2c/drivers/i2c_adapter/module /sys/bus/i2c/devices /sys/bus/i2c/devices/9191-0290

same here , all i2c support disappeared in moving from 079-r1 to 081-r1 previously working sensors no longer exist , all steps to detect sensors fail : no sensors , no devices etc.
This is a sensors-detect issue, not a udev issue.
hmm here we have a situation where something that has worked before (sensors-detect) has not changed but something thats responsible for that failure (udev) has changed. would you please elaborate on why its sensors-detect responsible and not recent changes to udev ?
Because the sensors-detect code was trying to do odd things in detecting udev (there is a standard way to do it...) udev changed and sensors-detect didn't get fixed...
