Who should I write to about this OOPS in 2,6,11-mm3?

[miles.lane@gmail.com (Miles Lane)]

I narrowed the problem down.
In the following scenario, the OOPS occurs:
CONFIG_I2C=y
CONFIG_FB_NVIDIA=y
CONFIG_FB_NVIDIA_I2C=y

If CONFIG_I2C is changed to build as a module, no crash occurs.
If CONFIG_FB_NVIDIA_I2C is not set, no crash occurs.
If CONFIG_FB_NVIDIA is changed to build as a module, no crash occurs.

Here is start of my dmesg output for a successful boot with CONFIG_FB_NVIDIA=m:
