           Summary: kmail hangs or causes desktop to hang when used with
                    Nouveau graphics driver
           Product: Mesa
           Version: unspecified
          Hardware: Other

            Status: NEW

syslog output when kmail causes kmail/desktop to hang

System Config, KDE Neon LTS 5.8.7, Nouveau driver 1:1.0.12-2 as described by
Ubuntu 16.04.1 LTS. Nvidia GeForce GTX570M, kmail 5.5.2.

Kmail will become unresponsive when attempting to scroll or click left on an
email. Sometimes just the controls/buttons in kmail will be unreponsive but
sometimes the whole desktop will become unreponsive and freeze, requiring a
ALT-SYSRq RSEIUB command to reboot system, ALT-F1 not working. If instead I=
 use
the Nvidia 375 driver the problem disappears, so this problem seems to be
related to the use of the Nouveau driver. syslog reports the following erro=
rs..

It also generates a second different error on some occasions ie a FIFO read

This error tends to hang the entire desktop, hence why I have attached a ph=
oto
of the tail -f /var/log/syslog output.
