Make sure you have File Systems > /proc file system support enabled
(CONFIG_PROC_FS). In theory i2c-proc should depend on it (in Config.in),
but now it looks like it doesn't...
Another possibility is a problem with symbol versioning, which you seem
to have enabled. It should work, but maybe you could try without
versioning, just in case.
Hope that helps,

It's enabled.

I have no idea either how to enable or disable symbol versioning. Have
never had to do anything about this before in previous i2c releases
compiled on the same machines.

This is enabled at kernel compilation time in Loadable module support >
Set version information on all module symbols.
You didn't tell us how you are installing i2c. Have you patched your
kernel sources tree? Or are you compiling i2c separately? In the latter
case, is the kernel a stock one or did you recompile it at some point?
Can you share your kernel configuration file so that I try reproducing
the problem?
Thanks,

My process
1) take the kernel-source rpm as it comes from RedHat
2) recompile it as it is
3) compile the i2c sources separately, but pointed at the
kernel configs and includes in that kernel tree.

Kernel config is just the one that would be in
red hat 2.4.21-32.0.1.ELsmp. I haven't changed anything.
Can send by separate E-mail if you want.

It appears that this problem was due to my mistakely compiling
the modules for a SMP kernel with a uniprocessor kernel config.
Have fixed that, and things load OK now.

Oh, great. This explains why I was unable to reproduce the problem, no
matter the kernel version nor how hard I tried.
Anyway, glad you finally figured it out. I'll try to remember in case
others report the same problem. It was really not obvious what the
problem was from the logs alone.
