Hello,
I am having a little issue running flexus after flex points have been
created.
I successfully created flex points for a solaris sytem I installed using
Simics.
However, when I run the simulation using the run_job script, it seems to
crash when initializing sys-uarch.

Does everybody know where the bug might be?
Thank you!!!
