Here is the skinny!

SGlist with a 2 byte boundary error on the FIFO's 510-511 or is 509-510

It all is determined on if 1 or 0 is starting as the counting number.
The FIFO flush to generate the interrupt is a DMA quirk. Similar to the
the 8K FIFO Phy issues in SATA.

Buy me a Coke (Red Can, no BLUE Crap) and we can discuss the issues.
