Anyone have any ideas?  If so, care to join this linux-kernel thread?

Subject: i2c: lost sensors with 2.6.10(-mm1)

Hi...

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 !!!
(the isa bus)


Debug output from 2.6.10-mm1:

Some ideas ?

TIA
