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?
Daniel
It has 4 GB.
Upgraded my machine now to 4GB, but I still can't reproduce this bug. Pedro, can you send your config, please?
Daniel
Here it is. It is configured for realtime and TuxOnIce patches. However, the bug still occurs without these kernel patches.
