Agh!  Actually, it looks like you might have been the victim of a bug
that was introduced that caused the external cache to not be manipulated
properly by the DMA code on 345/375/400 systems.  Mycroft has since
checked in a change to fix it.  I will be reorging that code soon to
make such accidents less likely to occur.

If you boot a GENERIC kernel, you should be OK, so that you can update
your sources and build a new kernel.
