Illegal instruction error on MIPS 79s334A with kernel version 2.4.3

[Venkata Rajesh Bikkina <rajeshbv@intotoinc.com>]

Hi all,
I am facing a strange error in an user mode application. I am running this
application as daemon in background process.
The error i am getting is 

[iked:41] Illegal instruction 00000000 at 8036b364 ra=8036bb78
Got ri at 8036b624.
[iked:41] Illegal instruction 00000004 at 8036b624 ra=8036b5ec
Got ri at 8036b650.

It is continiously displaying this error upto several seconds and then
stopping. The daemon is also getting killed.
I have aplied fast-sysmips patch by florian to my kernel. Still could not
get rid
of it. Can anybody through some light on this.

Thanks,
