i2c modules: Unknown symbols and parameters


I am running -current, and I recently had to reboot. Subsequently I have had trouble installing the nvidia drivers and getting X to start. When my machine boots up, I get a great number of warnings and errors about i2c related symbols and parameters. Here is a dump of `dmesg | grep i2c_`:

Can anyone give me some idea what may be causing this? I2c is compiled as a module, and debugging is enabled. I get these error messages when booting into 2.6.18 and 2.6.16.14.

I had the same problem ... in my case the first line gives the clue
Quote:
i2c_core: Unknown parameter `i2c_debug'
I searched in /etc/modprobe.d if this option has been set ( ls | xargs grep i2c_debug). In my case it was set in bttv, so I commented it out and rebooted my PC.

When consulting dmesg again all my i2c_core errors were gone

Hope this helps.
