Hi,
I was using PARSEC with gem5, it ran well for all the benchmarks,
but with prefetching turned on i am getting this panic. The prefetcher i am
using is ghb, i haven't changed a single line of code.
The panic is - Kernel panic - not syncing: Attempted to kill the idle task!
This is the content of system.terminal
