Hi Andreas, Thanks for the feedback. Actually I will be moving forward with the ARM ISA in the future, but I needed to run these benchmarks on MIPS for perform a comparative study on runtime, performance and power. And since I am somewhat new to gem5 I was also hoping to use this to learn how one should go about debugging errors like this.
