I've been running 3.17-rc4 plus the ext4 dev patches and due to either regressions in i915 or the X server (not sure which) over the last couple of weeks, I've had to power-down my system a number of times after the system has hung when either shutting down the X server or when trying to add or remove an external display. So I've had to unfortunately do a fair number of hard-power-offs on my T540p, and I've not noticed any like what you've described. Can you give any more details? Are you using LVM or dm-crypt? Is this repeatable?
