Comment 113 for bug 1766076

#106 The described symptoms are so specific that it would be a really surprising coincidence if my issue had a different cause with so identical symptoms.

Are you sure this is really about the dock?
What if it was actually about the thunderbolt controller on the motherboard instead?
I assume most people who post here also have similar computers (being Dell consumers).

Another argument supporting this theory: the system switches to the faulty mode after a suspend/resume of the computer. Nothing you do with just the dock triggers the faulty mode until you suspend/resume the computer and, after that, nothing you do with the dock (including powering it down and up again) will switch the system back to the non-faulty mode until the computer is powered down. Moreover the system switches to faulty mode as soon as a computer suspend/resume occurs, even if no thunderbolt dock was actually plugged in yet when the computer was suspended.

Of course I don't know what are the results of the investigations so far, so I may be completely wrong. But then it would be very interesting to know the explanation.
