Hi Wolfgang, As far as I remember, the hardware designer and I had checked that: we were using the right interrupt, it was triggered and the interrupt driver received it, but somehow in the driver the line state evolution from 'init' to 'up' was lost. Unfortunately, we did not have enough time for messing with the kernel then (1), so we tried alternatives, and disabling MDIO worked, so we did not investigate further. If you think it could be useful, I could reproduce that setting and do some tracing. All the best, Albert. (1) I can't believe I just wrote that, considering that I have just modified i2c-algo-8xx.c extensively (and i2c-rpx.c also, but more slightly) to get I2C_RDWR ioctl working, two days before project deadline. :) ** Sent via the linuxppc-embedded mail list.
