Subject: Question concerning memory initialization (4M->64M)

I have run into an interesting problem and would like to run it past
this newsgroup
to see if anyone has any experience in these areas.  I am running kernel
2.3.22 and
have upgraded my memory space from ~4M (0x400000) to ~64M (0x4000000).
I run the 4M
version of the kernel and have no problems but when I run the 64M
version, I run
into problems during the mem_init() portion of the code.  Specifically
during the
free_page(tmp) call during the determination of totalram, codepages and
datapages.
It looks like it is failing during the call to remove_mem_queue() within
free_pages_ok().
I am seeing the next->prev and prev->next  set to 0 causing a page
fault.   Is there
anything that anyone is aware of that I would need to change (beyond
mips_memory_upper)
that would enable me to increase available memory to 64M.  Any insights
would be greatly appreciated.

Thanks
Jeff
