DRM preventing my box from booting (BETA OR NOT) is UNACCEPTABLE. The fact that there has been no word from LT on this yet is UNACCEPTABLE. Guys, sort out your PR - please! It's a running joke!!

If it truly is a "kill-switch" meant to protect data from a potential fatal bug, couldn't it be handled a little differently? Instead of stopping it from booting, couldn't it boot into a "degraded" mode. As in, the array doesn't auto-start on boot. And in order to start the array, a dialog could be prompted warning the user of the potential danger, then they would make the decision to start the array.
