Hello. I will do this test ASAP. For now, I have made a good discovery. It has nothing to do with the docking station. It only happens when I have an external monitor connected (DisplayLink).
When I connect my external monitor, I can reproduce the freezes. When I disconnect it, they disappear. 100% reproducible. ** Description changed: Hello Since a few kernels back (or some other package?!) I get freezes every ~ 30-35 seconds. I can see this because if I play a video, it freezes. If I type something, it freezes. If I move the mouse pointer, it freezes. - I ONLY get this while being docked. + I ONLY get this while having a external monitor connected via + DisplayLink. Either directly to the laptop or via myu docking station. Computer is Lenovo T520 and I have the Thinkpad Mini Dock Series 3. + + Monitor is a 24" Samsung widescreen. Rebooting does not help. This is 100% reproducible.
