I can confirm this behaviour for my T450s runnig 15.04 with 3.19.0-30 kernel. Using the same workaround to input my dm-crypt password. Only one system freeze so far, kernel log also stating repeatedly
[drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)! But I can't confirm this issue for 3.19.0-28-generic kernel. Currently using this kernel as fallback and everything seems to work fine.
