Ok, thanks. If I can try anything that might help track down
the problem, please let me know.


Try this patch which is meant to be used in combination with the previous
patch.  It moves a test which determines if we actually need to perform a
cacheflush to the right place.  That's a bug which is harmless on UP but
a severe bug on SMP.


Also tried it on this morning's source (without the
most recent patches). Doesn't make a difference.
Still works with 512 MB and crashes with 1 GB.
The problem is not SMP related anyway. It appears
the same with an UP kernel.

Thanks
