Bug Description
System: T400s with external Dell Ultrasharp 25" monitor in DisplayPort.
When I boot ONLY the laptop dmesg output is clean, but once I connect the external monitor I will get the following. The same call trace appear also occasionally, when video streams freeze totally while the audio is playing.
This might be related to earlier similar problems, but didn't find exactly same, so reporting a new bug.
