Hi,

I am trying to boot linux on MIPS processor based board. Just when the kernel is trying to fork a new thread for the very first time in the boot sequence, I receive the "Unable to handle kernel paging request at virtual address ff200200" message which ends in kernel panic.

Following is the crash dump:

Unable to handle kernel paging request at virtual address ff200200, epc == 8010467c, ra == 80112fe0 >> This is the address of last but one statement of function kernel_thread.

Oops in fault.c::do_page_fault, line 213:
