You don't have i2c_core module loaded and none for your smbus chip (i2c_i801 in my case). I can't help, becouse I don't know what smbus chip your have. You can try to load modules manualy and see what dmesg says about.
Try modprobe i2c_i801. If you're lucky, devices will appears as expected.

Andrey,

I performed the steps you recommended and I don't even see any entries in /sys/class/i2c-dev/ like they did in the link you provided.
My OS is ubuntu-server 14.10 and I have ubuntu-mate 14.10 running on a laptop where I do get those entries so it may not be OS related.
Is it possible that the BIOS is blocking it?

$ ls -l /dev/i2c
ls: cannot access /dev/i2c: No such file or directory

$ lsmod | grep i2c

Check output of ls -l /dev/i2c-*
Here is example of my system :
crw-rw---T 1 root i2c 89, 0 Май 3 07:53 /dev/i2c-0
crw-rw---T 1 root i2c 89, 1 Май 3 07:53 /dev/i2c-1
crw-rw---T 1 root i2c 89, 2 Май 3 07:53 /dev/i2c-2
crw-rw---T 1 root i2c 89, 3 Май 3 07:53 /dev/i2c-3
crw-rw---T 1 root i2c 89, 4 Май 3 07:53 /dev/i2c-4
crw-rw---T 1 root i2c 89, 5 Май 3 07:53 /dev/i2c-5
crw-rw---T 1 root i2c 89, 6 Май 3 07:53 /dev/i2c-6
crw-rw---T 1 root i2c 89, 7 Май 3 07:53 /dev/i2c-7
crw-rw---T 1 root i2c 89, 8 Май 3 07:53 /dev/i2c-8

If you don't have any entries, check output of lsmod | grep i2c
Should be like this :
i2c_dev 12949 0
i2c_i801 12670 0
i2c_algo_bit 12713 1 i915
i2c_core 19116 7 i2c_algo_bit,i2c_i801,drm,drm_kms_helper,i915,videodev,i2c_dev

As you can see, here is i2c_dev module loaded and i2c_i801 driver used.

Than check this link: http://www.linuxquestions.org/questions/linux-newbie-8/no-dev-i2c-0-entry-after-insmod-i2c-dev-896482/ - may be related

Andrey,

I have tried that with both "acpi_enforce_resources=lax" and "clocksource=acpi_pm" enabled.
This is what I get:
$ sudo modprobe i2c-dev
$ dmesg |tail -1
[185273.767867] i2c /dev entries driver
$ sudo i2cdetect -l
$

Perhaps my BIOS is blocking access to the i2c buss? It's an HP server.
