Subject: Hard system hangs after upgrade from 18.0.5-1 to 18.1.1-1
From: Josh Triplett <josh@joshtriplett.org>
Date: Thu, 14 Jun 2018 00:00:39 -0700
Message-id: <20180614070035.GA4113@localhost>

Package: libgl1-mesa-dri
Version: 18.1.1-1
Severity: important

Severity "important" because it hard-hangs the system, but not RC
because presumably it doesn't happen on all configurations.

After upgrading all the mesa packages from 18.0.5-1 to 18.1.1-1, I can
consistently and quickly hard-hang the system by visiting almost any
non-trivial webpage in Firefox. The symptom is that the loading
indicator and all other display updates will freeze, the system will
stop responding to keystrokes (including alt-tab or ctrl-w), and the
mouse cursor will temporarily keep functioning but stop working if I
move it to the upper left corner to trigger the (gnome-shell) overview.

I reproduced this several times in a row (with reboots in between). I
then downgraded the mesa packages back to 18.0.5-1, and the problem
stopped occurring.

(Note that the information below comes from the system after downgrading
to 18.0.5.)
