Subject: Problem when the CPU cache is turned on
Date: Wed, 29 Dec 2004 10:22:22 +0530 [thread overview]
Message-ID: <41D23806.BC19A3C9@procsys.com> (raw)
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
