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
We may want to start over, since the original issue is now fixed and we
have a new issue with undocking.
Can you test the 4.7-rc4 kernel to see if the un-docking issue also
exists in mainline? It can be downloaded from:

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!
Can you try a newer Xenial kernel, to see if thise crypt issue is just in older
kernels.
https://launchpad.net/ubuntu/+source/linux/4.4.0-10.25
If 4.4.0-10 can boot without the crypt bug, see if it has the docking
bug.
Thanks

Are you able to boot either of those kernels if you bypass the GUI?
This can be done by removing "quiet splash" from the /etc/default/grub
file, then running sudo update-grub.
You'll still get prompted for the decryption password, but it will be a
non-graphical prompt.

Sorry for the late reply. I've tried testing both those kernels, but couldn't

Since this bug does not exist with any of the upstream kernels, it may
be due to a SAUCE patch. Can you test the following Ubuntu kernels:

I can confirm that this still happens in the kernel from -proposed,

mistaken). I've added the appropriate tag back to the bug.

when you install a new kernel package it becomes the default kernel that
