best wishes, Nethra

Hi geeks, i am trying to bring up the latest kernel on EP8248 target, i am using U-boot-1.3.2 and linux-2.6.25-rc8, i started debugging using

BDI2000 which helped me to >know atleast what is going wrong, i have added some printk's in the kernel source but still i am not able >to find where and what exactly is going wrong, The first statement it is printing in the log buffer is

""Using Embedded Planet EP8248E machine description"" and thats it the next

message is

Unable to handle kernel paging request for data at address 0xbfff0000

Faulting instruction >address:0xc0012070 (This nearest address to this address in System.map file is cacheable_memzero)

and tracing like this i came to know that in the file

arch/powerpc/mm/ppc_mmu_32.c , here in the >function __init MMU_init_hw() and in the line n_hpteg = total_memory / (PAGE_SIZE * 8); >probably it is getting problem because when i tried to print the variable total_memory it is printing >zero !!! :( :( so probably i am thinking it is not able to find some memory for Hash table :(

Please share your knowledge and skills and help me to resolve this issue.. thanks :)
