Christian, did you happen to try removing the i2c-powermac driver
before?

Well, I definitely removed the driver before, but I'm not sure if I ever 
read the /sys files after doing this :-\

I am curious if this is a recent problem, possibly caused by
changes to the i2c stack, or if older kernels already had this problem
and nobody ever noticed. I suspect the latter.

Fair question, but I really could't tell. I realize a bisection would be 
helpful, but I don't think I'll have to time to do this on this machine 
(it's a PowerBook G4, but kernel still compilation usually takes ~30min) 
and I'm not sure that I care _that_ much about this particular issue. 
I just wanted to report this one, for the sake of the archives, as noone 
else seems to be bothered by it anyway...

I think that sysfs files creation should be moved to the end of
probe_thermostat() and sysfs files removal should be moved to the
beginning of remove_thermostat(). Something like the totally untested
patch below (no ppc machine at hand):

OK, thanks Jean - I'll give it a try later today and let you know.


Thanks again,
Christian.
