Hi,
Sorry for losing track of this. My current situation is that on the
latest xenial kernel (4.4.0-31-generic) I can happily dock and undock
without the laptop freezing.
... instead, after undocking the laptop freezes when trying to suspend.
I'll do some investigation, and if I can't figure
Hi Joseph,
Sorry, but I haven't gotten around to trying the last kernel you posted.
In the meantime, Xenial had a new kernel released: 4.4.0-25-generic. In
this latest kernel, I can now dock without everything freezing - yay!
However, I now can't undock without everything freezing - booo!
It just happens with the last two kernels you linked to.

Hi Joseph,
I tried with the 4.3.0 kernel, and I'm unable to enter the password in text

Hi Joseph,
Sorry for the late reply. I've tried testing both those kernels, but couldn't
boot wither either of them: I have full disk encryption set up on this laptop,
and when booting these kernels I'm unable to enter my decryption password. The

I can confirm that this still happens in the kernel from -proposed,
although it's possible it's less frequent (not sure about that, I may be
mistaken). I've added the appropriate tag back to the bug.

Ugh - sorry about this, but I realise I've messed up. I assumed that
when you install a new kernel package it becomes the default kernel that
grub boots. I now know that's not the case.
I've gone back and re-tested all the mainline kernels: 4.2.0, 4.3.0,
4.4.0, and 4.6.0 all work perfectly with

Public bug reported:
Since upgrading to Xenial, about 80% of the time when I dock my thinkpad
laptop I get a complete system freeze. The symptoms of the freeze are:
* The two external monitors connected to the dock seem to be in a half-
configured state - they're powered on, and display some
