Hello, Yoichi

and thanks for reply.

May this be caused by hardware error/bug ?

I ran 'objdump -d /tftpboot/vmlinux | grep -B7 ^80256e14' and got the 
following:

80256df8:       732f6330        0x732f6330
80256dfc:       64347000        daddiu  s4,at,28672
80256e00:       63636973        daddi   v1,k1,26995

80256e14:       64367000        daddiu  s6,at,28672

But I'm not good in MIPS assembling. Does this give you some clue?
