Broken pygobject3 package dependencies prevent upgrade from Red Hat Enterprise Linux 7.1
The pygobject3-devel.i686 32-bit package has been removed in Red Hat Enterprise Linux 7.2 and was replaced with a multilib version. If you have the 32-bit version of the package installed on a Red Hat Enterprise Linux 7.1 system, then you will encounter a
yum error when attempting to upgrade to Red Hat Enterprise Linux 7.2.
To work around this problem, use the
yum remove pygobject3-devel.i686 command as
root to uninstall the 32-bit version of the package before upgrading your system.
Build requirements not defined correctly for Emacs
The binutils package earlier than version 126.96.36.199.1-54 causes a segmentation fault during the build. As a consequence, it is not possible to build the Emacs text editor on IBM Power Systems. To work around this problem, install the latest binutils.
External display issues when combining laptop un/dock and suspend
In the GNOME desktop environment, with some laptops, external displays connected to a docking station might not be automatically activated when resuming a suspended laptop after it has been undocked and docked again.
To work around this problem, open the Displays configuration panel or run the
xrandr command in a terminal. This makes the external displays available again.
Emacs sometimes terminates unexpectedly when using the up arrow on ARM
On the ARM architecture, the
Emacs text editor sometimes terminates unexpectedly with a segmentation fault when scrolling up a file buffer. This happens only when the syntax highlighting is enabled. There is not currently any known workaround for this problem.
