Mine definitely doesn't run exec's then, it's definitely in debug mode as I can ~help etc, however doing any exec command just refreshes the screen with no output shown, so for instance I can't execute the "uname -a" to determine if my Linux matches (which it presumably doesn't).
I wonder if the lab in in your linux relates to a lab build rather than general release. You don't happen to be one of the people amazon approached to be an early tester of the new "no freezing" firmware?
