I guess that even with normal permissions (which by the way I'd like you to show us) your "sensors -s" problem is still there? > > Second, try to write a value to an ordinarily-writable i2c file such > > as temp_max1.

Well, that was supposed to work ;) The common (and unsolved so far) problem is that people can write to the files using "echo" but not through libsensors (which sensors uses). > > Third, could you reproduce the problem with a non-mm kernel > > (2.6.2-rc1 for example). > > With 2.6.2-rc1 I still got the same Problem.

Yes it does. From what I can see there, you have a second i2c bus (a real one, as opposed to the isa emulation). Looks like there is much trouble on this second adapter. It is probably a completely different problem though. That said, please tell us what that second i2c bus is and what chips are present here, just in case there is some kind of interaction between both problems. Back to the initial problem, I'd like you to strace "sensors -s". I put a trap in there some times ago, maybe it'll confirm my suspicions. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
