ok, I can confirm that this patch fixes the problem for me too.
I was now able to read my I2C sensor 97388 successfully and only 2814
readfailures happened.
That means an errorrate of 2.8% that is ok for me.

I found now when it happens or better when it not happens.

I boot my icecube board via NFS. If the board is up and I unplug the
network I get no read errors.
If the network is connected (NFS server responding) I got read errors
on I2C with a rate of approximatly 3-4%.
Seems to be a problem with the network driver.

I can't reproduce your no-errors behaviour. I tried unplugging network
cable and compiling out the fec driver.
