[Kernel-packages] [Bug 1550779] Re: [i915]] *ERROR* CPU pipe A FIFO underrun - Xorg glitches
I actually switch back to my x230 and don't have the hardware for testing, but we should really bisect this issue so the current xenial kernel can be fixed. Anyone who wants to help can test those kernels https://wiki.ubuntu.com/Kernel/MainlineBuilds especially the late 4.4 and the early 4.5 i guess the fix came in between.

@Christopher To demand a full bisect for the status "confirmed" is IMHO much over the edge, especially as it takes some time to trigger the bug. @PocketSam Although Chrisopher's advice is right to follow, if you gather the information with which mainline kernel the bug disapers it would still be good.
