here is the output of the patch you sent me when the interference is triggered.
The log is long, 1.3mb in size.
I don't see anything suspicious. The transfer_buffer addresses repeat every 32 URBs, and the DMA addresses cycle almost entirely uniformly from 0x20000000 to 0x23ffffff in units of 0x2000 (there are a few gaps where the interval is a little bigger).
The DMA pointers do indeed look sane. I wanted to take a deeper look at this and set up a 64bit system today. However, I fail to see the problem here. Pedro, how much RAM does your machine have installed?
