you are right. I'm working with multiple sources from different sites
and missed the fact the original driver ide-jasper.c published at
uclinux.org has BMDMA undefined. Dmegs output was produced using a
slightly modified version of the file that has BMDMA defined, but
there are no other changes in it that would explain unexpected DMA
interrupt mystery, it should be one of the patches done to ide and
cdrom subsystem.

Here is an updated patch, could you please check it? I don't see
anything unusual except the "never disable DMA" logic in ide_dma.c.
