Hi MikeHi all. This is a revised version of my previous patch to fix negative temperature readings of the LM77 in kernel 2.6.x.Bye, Mike I'm back in the civilization ... I have applied the old patch not this one but the changes from the new are marginal so this doesn't solve the problem (see below). With the old patch I get the following output current:0 low:0 lowHyst:-1 high:0 highHist:0 critical:0 criticalHyst:0 instead of negatives ones but it's still the same. The driver 'hangs' and gives no more other values than this ones. What I have seen now is that removing all modules and inserting again does not solve the problem even a reboot does not work so It seems that the drvier is doing something nasty with the hw ... After removing inserting all modules for i2c the Directory 0-0048 did not exist of path /sys/bus/i2c/drivers/lm77/0-0048 I had to do a power off/on of my wrap board so the temp. could be read again right. The next time the error ocurred I tried to reboot without removing modules. Same thing, a reboot does not solve the problem, so something really needs to be reseted !!! The funny thing is that this occures on one wrap board on the other not (both the same patch) I have to test other wrap boards. As I remember it was not only onre board so an hw defect is improbable but maybe a design error ...
