Public bug reported: I can reliably make Linux freeze.
If I boot past the cryptsetup password dialog into GDM (I think), attach a docking station, unattach, then reattach, the system freezes. At least I cannot move the mouse cursor anymore, switch VTs, reboot, num lock doesn't toggle. I think it works well when *not* booting into GDM, but staying at the passphrase dialogue of the initramfs. I'm having a Thinkpad X240 with two external monitors. This is the standard ubuntu kernel, I haven't tested upstream kernels just yet. I'm intending to test with linux- image-4.6.0-040600-generic_4.6.0-040600.201605151930_amd64.deb from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-yakkety/ now.
