This appears to be the same bug that was present, two kernels ago:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813795
I switched to the 46 kernel from the 45 today, and noticed my tablet hangs when its plugged into the docking station. Without the docking station it appears fine. As with the previous bug, even when it hangs, I can ssh into the tablet. So it appears to be the user interface that's frozen. The mouse pointer remains mobile.
Note: this run of apport is pre-crash.
Note 2: I encountered this bug three boots in a row yesterday. But today I have been unable to duplicate it. So I'm a little confused. I'll try to duplicate the bug again tonight. If I can't, I'll close this thread.
Note 3: I have been unable to duplicate this bug. Please consider this case resolved. If I can find a way to duplicate it, I will start another thread.
