Hi All,
I've been running GEM5 on OS X Lion with no problems until now, but
I've come across a problem since moving away from the stable repo.
When I use arm_detailed (either restoring a checkpoint, or indeed
booting from scratch) I get the error below. I do not see the issue on
Ubuntu 12.04-64bit.
Thanks and regards,
Stuart.
