Not a definite answer by far, but a friend of mine has been trying (for a
little over a week), to get NetBSD 1.4.1 installed on his SPARCstation LX
and SPARCstation IPC. He gets DMA timeout errors when the NetBSD installer
gets to the partitioning/slicing step, and encounters them a little
further on with the IPC. Reproducable every time. There is nothing extra
in either of these machines, save a CGThree in the IPC. 

Both are from a floppy install... boots the kernel and gets into the
mini-root just fine.

I recall from the OpenBSD web page that a new version, 2.6? Is being
released December 5th or 6th... perhaps some bugs are worked out..

Have fun.
