Hi Nilay,

You are right. I fixed this but I still get errors with smt:

# build/X86/gem5.opt configs/example/spec.py --cpu-type=detailed -n 1
--cmd="burnP6;burnP6" --caches --l2cache

panic: Unrecognized/invalid instruction executed:

{
leg = 0,
rex = 0,
 op = {
num = 1,
 op = 0xdc,
prefixA = 0,
prefixB = 0
 },
modRM = 0xdc,
 sib = 0,
immediate = 0,
displacement = 0
 dispSize = 0}

 @ cycle 515088
[invoke:build/X86/arch/x86/faults.cc, line 131]

This is with cpuburn program. But I have tried several benchmarks/commands
which work fine without smt. Not sure what could be the reason.. any ideas
folks ?

Regards,
Ankita
