Comment 5 for bug 1503572

I can confirm this bug for my ThinkPad T450, model 20BV001BGE running 15.04 for kernel 3.19.0-30 and 3.19.0-31. Plus, something maybe interesting, when using these kernels the intel-linux graphics installer doesn't recognize the i915 graphics card.

If using the -28 kernel, the system is stable, I don't get the "The master control interrupt lied (SDE)!" error message and the intel-linux-graphics-installer recognizes the graphics card and runs smoothely. Hope this helps.
