CPU stuck message in Ubuntu 12.04 (Virtualbox, OSX host) #66

Hello there. I've been trying to use dtrace4linux in Ubuntu 12.04 server with little success. My latest attempt was within a Virtualbox VM, hosted in OSX (I understand that's mostly how you test the port). From a fresh install, I upgraded all packages, then upgraded the kernel to 3.20-51-generic. Then git cloned dtrac4linux, ran tools/get-deps.pl, make all, make install, make load, make test. I haven't figured out how to cut and past from the VM screen, so here's a screenshot. Any suggestions will be more than welcome. Also, is there any other site where dtrace4linux users gather to support each other, cry on each other's shoulders? Here it is:

I forgot to mention I changed the tests.pl script to pass -w to dtrace, as I had experienced the deadman mechanism before on a different Ubuntu 12.04 box, which completely froze. That was on real hardware, same kernel.

Another bit of information I failed to mention: this happened during the fbt-a test.
