Dear all:
I use kernel 2.6.18 and I get the kernel panic as below:

Hmmm, your machine is not x86, is it? So, I guess this panic is caused
by unaligned memory access.
Yes, my machine is mips machine.
if do_ade in unaligned.c is a trap, where do we register it?
I grep the source code but I only find the definition but cannot get
the place where we register the trap.
Look in genex.S for lines like:
BUILD_HANDLER adel ade ade silent /* #4 */
BUILD_HANDLER ades ade ade silent /* #5 */
And also in traps.c for lines like:
set_except_vector(4, handle_adel);
set_except_vector(5, handle_ades);
