I know it's an old bug but I'm still stuck with the I2C errors. I'm using Ubuntu 8.04 with kernel version 2.6.24-23 (upgraded from 7.10), and the errors are still there. I recently upgraded v4l drivers and switched to 1.20 firmware, with no luck. I also tried the delay solution founded by hugolp. Is it possible to continue with this issue? Here's an extract from my syslog:
