does any one succeed running a functional FEC and ATA (pata) running
together?

Yes, we do, on the phyCORE-MPC5200B-tiny; you can check our patches here:

thanks, my kernels are already patched and still observing that kind of
behavior. I'm using Domen's new FEC code and ATA from 2.6.24-rc2.

playing with the XLB Master's enable and priority lead to significant
changes (good ones) in the rate of corruption appearance. I'm afraid of
the "new" priority I've set, as that may lead to lockups on the XLB,
still investigating.

Do you have a reproducable test scenario we can try on our hardware?
