No devices?  Does 2.5.68 work for you?

Same deal with 2.5.69.

Ok, but 2.5.67 worked for you, right?  Care to do a binary search
through the different -bk trees inbetween to find where it stopped
working for you?

[Ed Sweetman]

hey guys.  Notice a missing proc driver? hint: i2c.    That's why 
sensors wont work even when you load the modules. At least that's what i 
can tell from what the lm_sensors page mentions and what not.

Huh?
The i2c code now interacts to userspace through sysfs, not /proc
anymore.  CaT is properly looking for his sensors in sysfs.

Here's what happens when looking through sysfs on my box running 2.5.69:

# find /sys/ | grep -i i2c
/sys/bus/i2c
/sys/bus/i2c/drivers
/sys/bus/i2c/drivers/lm75
/sys/bus/i2c/drivers/lm75/0-0048
/sys/bus/i2c/devices
/sys/bus/i2c/devices/0-0048
/sys/devices/pci0/00:1f.3/i2c-0
/sys/devices/pci0/00:1f.3/i2c-0/0-0048
/sys/devices/pci0/00:1f.3/i2c-0/0-0048/temp_input
/sys/devices/pci0/00:1f.3/i2c-0/0-0048/temp_min
/sys/devices/pci0/00:1f.3/i2c-0/0-0048/temp_max
/sys/devices/pci0/00:1f.3/i2c-0/0-0048/power
/sys/devices/pci0/00:1f.3/i2c-0/0-0048/name
/sys/devices/pci0/00:1f.3/i2c-0/power
/sys/devices/pci0/00:1f.3/i2c-0/name

Which is what should be showing up on CaT's machine (of the lm75 device
is on his hardware.)

Hope this helps,

[Ed Sweetman]

Ok, then the sensors program that is part of the lm_sensors package is 
just not up to date with the drivers since it complains about no 
i2c-proc and has no options for looking at sysfs.

My via686a sensors seem to be working just fine in .69

Yes, the libsensors code has not been updated yet, sorry.  I'm hoping
for some unification with the acpi/power management people too, as they
too care about power and temperature and fan settings.

Yes. And ofcourse it isn't so I feel like a right boob. Now, compiling
the right sensor (adm) gets it registered and promptly crashes the
kernel. Once this happened whilst in the kernel, either mid scroll of
the fb or mid write of a new line on screen and another time this
happened mid-fsck (no partitions needed fscking). Witht he wrong/no
sensors module in the kernel runs just fine.

My experience with the sensors code is evolving. :)

Thats strange. Mine don't, and never have in 2.5 - works in FreeBSD just
fine though.

Does the 2.4 packages from the lmsensors web page work for you?  And if
so, are the drivers your hardware needs currently in the 2.5 tree yet?
If not, want to port them?  If so, please let us know.
