GrabFSPages causing exception

Hi

I am working on a BSP cloned from mainstone II on pxa270 processor. We are
downloading the image using ARMBOOT (over serial port). The execution flow
that we see, the image is executing upto GrabFSPages and is causing an
exception in RemovePage function in GrabFSPages (in private directory).
The flow goes like:
Startup->OALStartup->KernelStart->ARMInit->OEMDebugSerialInit->OEMInit->KernelFindMemory->GrabFSPages.
The last message the we get is:
Booting kernel with existing memory configuration:
