Mouse moves normal for one second, then completely stops for roughly one second, then moves again for a second.
The whole repeats infinitivly.

This commit has no mouse lag: e0a1e7abb95f53e4b0c633f57fbd3ba163a98e73
This commit has mouse lag: d6c92fb146a95bd38feaa94c8d2bafda63600e8e

I first assumed it is either one of the commits related to evdev support, so I reverted them:

d3d1dd3e4513b2ab753f8ba52f144dc916420ba6
    3ea800bb832ad69c10f85ce9bce98efd8e892285
    eaf0d054af4aa304548c1efc497aad966b86a590

But the mouse lag still happens. Next I reverted the recent drm/radeon commit:

d235ee5f3490f63ba738915974154a0e2e49378d

But mouse lag still there. So I assume it must be one of dillon's commits on 5th or 6th December.

Anyone else seeing the problem? I can easily bisect the problem, as it's only 6 commits. But maybe dillon can see the problem faster.
