SubjectRe: FW: PDC202XX DMA loss in 2.4.21-pre3-ac4

Yeah, I know a good friend of my is the author.
Since he is not available to comment, you can believe as you wish.

Read the code and read the ioctl transport, you can not get there from
here, period.

So the 28-bit Smart was never executed, however the 48-bit was.
You can't get the meaning full data.

I am out of this arguement, go read the spec.

Cheers,
