|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.
high memory: 0x83fff000 start memory: 0x80433000
