I have linux-2.4.23-rc5 and more or less all the previous kernels back
to know what and a plextor premium 48x and have no problems, with or
without dma.
I guess that you have a problem with
* either your chipset (is it via, nforce, or what)
* or your cables (too long, too twisted)
I would suggest first:
* put the burner as single master and look if it is the same
* put it on another ide controller
It may be that the plextor drive is damaged and cannot do dma.
Best wishes
