kernel crashes when you running system profiling? or you running profiling to see why it is crashing?

Without seeing the complete shutdown message (eg. the register context)
it's hard to say exactly what the cause of the kernel crash was.

The SIGBUS "signal" code you see (10/1/5) is usually the result of a
misaligned access.

Do you have an up-to-date BSP?
I seem to recall there was a bug in the timer_value callouts for some
of those atmel parts that would cause stack overflow issues with the
kernel instrumentation code.

Elena: the kernel crashes when i  do event trace from Momentics. So when i try to profile my system it crashes.
Sunil : The kernel dump does not show the register contex, it prints out exactly what i writen in my first post. I am 
using the latest Momentics SDP , with the instrumented kernel.
