Public bug reported:
Hi,
Since I updated to kubuntu 16.10 I quite often have the situation that
my laptop completely freezes after login in sddm (that means: while KDE
is loading).
During that time:
- Fans run high
- laptop is completely unuseable (no mouse or keyboard-input accepted, can't
switch to other terminal, etc ...) - only a long press to the power-button
helps .
- network-connections break (tried to monitor the system remotely, but when the
error occurs, also the ssh-connection fails)
- the kern.log stops and contains only a few lines of rubbish:

...
- installed and tested kernel-crashdump, but in this situation it is not
triggered (or fails to write a coredump)
- (once I tried to leave the machin alone for about 30 min, it does not
recover...)
As a last resort, I installed netconsole and captured the kernel.log on
a remote machine, this revealed, that during the lookup, following "soft
lockups" occur:

lsb_release -rd
Description: Ubuntu 16.10
Release: 16.10
(using kubuntu)
uname -a
Linux orbit 4.8.0-28-generic #30-Ubuntu SMP Fri Nov 11 14:03:52 UTC 2016 x86_64

Attached tgz contains:
- the log taken from netconsole
- the kernel-log from the frozen machine (the netconsole.log belongs to the
freeeze at "Dec 3 14:09:40")
- the output of dpkg -l (to provide a full list of installed packages/versions)
The issue occurs approx. every 3-4 logins, regardless whether it's a
