More a crash than a freeze. 
I thought it was a freeze because the taskbar was still there.

I met the freeze again. 
In fact, this was not a freeze.
I looked at the plasmasheel processes:
$ ps -elf | grep plasma
0 Z collette  1776 1  2  80   0 - 0 task_d 18:11 ?00:01:18
[plasmashell] 
0 S collette 21709 12626  0  80   0 - 29882 -  19:01 pts/200:00:00 grep
--color=auto plasma

So, plasmashell was dead.
I killed it via a kill -15 and then restarted manually plasmashell ...

I've got no reaction to a right click on the task bar. But I don't remember if
I was able to get a reaction to a right click on the desktop. I think the
answer is no because I tried to start konsole to see what's happening. And I
must have done a right click on the desktop. But I will check.

How do I get a backtrace of the frozen process ?
How do I identify the frozen process ?

[plasmashell] [Bug 400667] New: Tasj bar froze when kde is run under kernel RT

2018-11-04 Thread ycollet
https://bugs.kde.org/show_bug.cgi?id=400667

Bug ID: 400667
   Summary: Tasj bar froze when kde is run under kernel RT
   Product: plasmashell
   Version: 5.14.2
  Platform: Other
OS: Linux
Status: REPORTED
  Severity: normal
  Priority: NOR
 Component: Task Manager
  Assignee: h...@kde.org
  Reporter: ycollette.nos...@free.fr
CC: plasma-b...@kde.org
  Target Milestone: 1.0

The Kde Task bar froze really often when I run KDE under a realtime kernel.

Everything in the taskbar is frozen (the clock, the menu, all the icons of the
launched application). But I am still able to use application (I switch between
applications using alt+tab).

I recover the task bar if I disconnect / reconnect from my session.

I use Fedora 27 + last KDE version.

Kernel RT is 4.18.12-rt8.
