Thanks. So, that means you don't have any bus from i2c-pasemi, since all
numbered busses it wants to have [0-2] are already taken by the Radeon
card. This has always been the case, no change in behaviour since 2008.
Only since last merge window, the I2C core just reports this conflict.
Maybe a bit too noisy?
I don't think using i2c_add_numbered_adapter is a good idea together
with PCI cards. I'd prefer to see i2c_add_adapter used. However, I don't
know the platform at all and if there is someone relying on a static
numbering scheme? I would assume this is not the case, because nobody
really noticed that the busses do not probe for a while. Anyone here
with more insight about PASEMI platform?
