I have seen this on a r4000 Indigo and a r5000 O2. I _strongly_ believe that
the problem is caused by CPU-specific cache botches in/around pmap.c -- swapping
the CPU modules with r4400 and r10000 make the problem go away.

Interesting. Are you sure this drive is good?

You have a revision 5 board. From newport.c:
/* Work around bug in some board revisions */
if (dc->dc_boardrev < 6)
x_offset = 21;
else if (dc->dc_vc2rev == 0)
x_offset = 29;
else
x_offset = 31;
My rev 4 NG1 works with the 21-pixel offset. Perhaps it should be used for
board revisions less than five rather than six?

Very odd.
