Nouveau - Feb 2019 - [Bug 109558] Plasma locks up after splash screen

https://bugs.freedesktop.org/show_bug.cgi?id=109558

            Bug ID: 109558
           Summary: Plasma locks up after splash screen
           Product: Mesa
           Version: 18.3
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/DRI/nouveau
          Assignee: nouveau at lists.freedesktop.org
          Reporter: qjztreez at outlook.com
        QA Contact: nouveau at lists.freedesktop.org

Output of dmesg

Operating System: Arch Linux 
KDE Plasma Version: 5.14.5
Qt Version: 5.12.1
KDE Frameworks Version: 5.54.0
Kernel Version: 4.20.6-arch1-1-ARCH
Graphics Card: NVIDIA GeForce GT 650M

Plasma locks up after splash screen, and it is sometimes (but not always)
possible to switch to tty2 and kill the session using loginctl. The magic SysRq
keys Alt+SysRq+REISUB and Alt+SysRq+REISUO always work though.

This seems to be a problem related to acceleration because adding the
'nouveau.noaccel=1' kernel parameter solves the problem, but disables
some
desktop effects as well.

Created attachment 143309
  --> https://bugs.freedesktop.org/attachment.cgi?id=143309&action=edit
Part of pacman.log

The problem occurred after upgrading mesa from 18.3.2 to 18.3.3 and qt from
5.12.0 to 5.12.1, but downgrading mesa to 18.3.2 didn't help.

complete freeze up as the splash screen starts flashes up then frozen .

i will try this evening to revert every thing in that log see if that
fixes the problem unless someone can point to one package that may be
causing the issue .
