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.
