wrong core dump information

[solmac john <johnsolmac@xxxxxxxxx>]

Dear All,

I am using one SMP arm board if my one Application thread crash on one
core(CPU0)
and some time i observe second core generate(CPU1) the core dump.

when i observed the core dump file i observe gdb is show CPU1 register
information.

kernel crash messages:-

Is this expected behavior ?

Is there any ARM patch which can prevent this ?

Thanks,

John
