Crash on reducing the kernel mem.

Hi all, I am using MIPS processor, with 256 MB RAM. currently I am using 128 M for drivers and 128 M for Kernel. I tried to allocate more memory for Drivers, surprisingly I got crash when I reduced kernel memory to 110 M. My debugging took me to USB controller, which was not reset in bootloader.
