CLR 1.1.4322)

Description of problem:
i2c modules missing from distribution, rendering lm_sensors non-

Running sensors-detect results in numerous errors similar to:

Load `i2c-elektor' (say NO if built into your kernel)? (YES/no):
modprobe: Can't locate module i2c-elektor
Loading failed (Illegal seek)... skipping.

Finally, the program ends with:
Couldn't open /proc/bus/i2c?!? at /usr/sbin/sensors-detect line 2970, 
<STDIN> line 7.

sensors-detect works fine on Fedora Core 3 Test 1.

Version-Release number of selected component (if applicable):

Steps to Reproduce:
1.  sensors-detect
2.  Answer yes to all questions

Actual Results:  See above

Expected Results:  Modprobe lines and an init script should be

George, did you install the kernel-unsupported package? IIRC, the 
-unsupported package provides i2c kernel modules. Maybe you've got 
to reboot the system, maybe "depmod -a" recognizes the new modules 
after installing the -unsupported rpm.
Comment 2 Andreas Thienemann 2004-10-02 18:13:39 EDT
Installing kernel-smp-unsupported or kernel-unsupported respectivly
makes lm_sensors work.

I suggest closing this bug with NOTABUG.
Comment 3 Phil Knirsch 2004-10-20 11:29:03 EDT
Closing bug.

Read ya, Phil
Comment 4 George Toft 2004-10-21 08:23:48 EDT
I feel installing an unsupported kernel in an Enterprise environment
is not a solution to this problem.  Is this resolved in the updates
for RHEL3?  Please advise.
Comment 5 Phil Knirsch 2004-10-21 08:43:51 EDT
The lm_sensors software and the related drivers are not supported in
the SLA, therefore the drivers of the lm_sensors package are shipped
in the kernel-unsupported package.

In order for you to use the lm_sensors kernel drivers you need to
install that kernel package.

Read ya, Phil
Comment 6 Timo Ofzo 2004-10-23 06:22:40 EDT
This does not work for me!

I installed the unsupported kernel (x86_64):

# rpm -q kernel-smp-unsupported
# modprobe i2c-proc
modprobe: Can't locate module i2c-proc
# rpm -ql kernel-smp-unsupported |grep i2c

Please tell me where to find the i2c modules.
