Not trying, is fixed :)

It concerns DMA operations where an external device is reading memory
from the ppc.

The patch is already in your CVS since June (IIRC). Since then I
noticed that the bug only affects XPC8245 processors (from the type
numbers and the age of the boards, I would think they are old
(prototype) versions).

The newer processors do not have this bug anymore and I have disabled
this patch for 4 months now on our firmware: none of the newer
production processors seems to be affected.

I don't know if many ppl are still working with XPC versions of the
8245. This is the reason I put #if 0 #endif around the silicon work
around the code again. Feel free to suppress the code completely.
