Hi! all,
This original message posted To: port-mips@ and port-evbmips@ by me.
Also this file too.

I cannot solve this problem... X-<
Thanks,

Hi! all
My MIPS Alchemy machine(OMSAL400) is reported on the error the other day
and doesn't boot.

I look the current kernel and the old kernel. The instruction is obviously
different.
current kernel:
8020b8a0 <mutex_enter>:
8020b8a0: c0880000 lwc0 $8,0(a0)
8020b8a4: 15000006 bnez t0,8020b8c0 <mutex_enter+0x20>

8020b8b4: c0880000 lwc0 $8,0(a0)
<snip>
old kernel:
8020a4ec <mutex_enter>:
8020a4ec: c0880000 lwc0 $8,0(a0)
8020a4f0: 15000006 bnez t0,8020a50c <mutex_enter+0x20>
8020a4f4: 00175021 addu t2,zero,s7

8020a4fc: 1140fffc beqz t2,8020a4f0 <mutex_enter+0x4>
8020a500: c0880000 lwc0 $8,0(a0)
<snip>
I do not know to solve this error. Do I only have to specify optional
CPUFLAGS? or other better method?
Thanks,
