Your kernel drivers all need to be compiled with the same ARCH setting, So,
try to compile your 3ware driver with ''make ARCH=xen'' as well.
(inserting an "ARCH=xen" line at top of your kernel toplevel Makefile
usually
forces that ARCH setting onto external module Makefiles automagically, so
there''s less chance of accidently forgetting it)
but if your driver contains some precompiled object code with no source
available, you''re probably out of luck...
Still I wonder why the kernel loads a module compiled for a different
architecture at all... Doesn''t it have any checks there, could I have
it load
and crash on e.g. a linux-ppc module on intel, given the symbols match?
