Hi, Iam trying to bring up a custom board with RM5231A MIPS processor and IT8172 companion chip. Right now i have an issue related to running Linux 2.4.25 on MIPS with cache enabled. When i run the kernel with CPU Cache enabled, i get the following error messages. A. "Unhandled kernel unaligned access or invalid instruction in unaligned.c::emulate_load_store_insn, line 493:" B. "Reserved instruction in kernel code in traps.c::do_ri, line 663:" C. "Unable to handle kernel paging request at virtual address 00000000 These errors happen when i run fsck, vi or a simple du command. When i trun on the "Run uncached" option these errors disapper. I do not know where to start debugging. Can any one tell me what could be the problem when the cache is turned on. regards priya
