consistent_alloc question

[jmartin]

   Hi:

      i'm working on a embedded platform based on mbx860. This board uses an
   mpc860T,no pci available. Since i update to montavista 3.1 i have
 problems
   in fec. Kernel don't boot, fec gives a transfer error ack signal, at
fec.c
   line 1737. debugging kernel, i can't access to cbd_base. I suppose memory
   map is  wrong. No pci bus available. consistent_alloc seems to get a free
   page, mark uncacheable, remove it from free_pages list, and map it.

    what memory zone is used by consistent_alloc? cbd_base seems contain a
   virtual address mapped to a physical address.
