Hello, I wrote:

Apparently, 'xcount' being 0 does not mean 0 bytes for TRM290; it means 4 bytes,
judging from the code immediately preceding this check.  So, we must never try
to "split" the PRD for TRM290.

This is probably never hit anyway -- with the DMA buffers aligned to at least
512 bytes and ATAPI DMA not being used for non block I/O commands...

Bart, unfortunately, drivers/ide/ide-dma-sff.c has the same mistake -- you probably forgot to modify the patch splitting it from ide-dma.c... :-/

MBR, Sergei
