Xorg.0.log
Dell 7510 laptop with Intel Xeon E3-1545Mv5 (Iris Pro 580), running Ubuntu
16.04 (stock except for kernel and linux-firmware package - using
linux-firmware 1.161 from Ubuntu 16.10).
The stock Ubuntu 16.04 kernel (4.8.0-22-generic) works fine.
Updating to kernel 4.9-rc4 or drm-next or drm-intel-next or drm-intel-nightly
from <a href="http://kernel.ubuntu.com/~kernel-ppa/mainline/">http://kernel.ubuntu.com/~kernel-ppa/mainline/</a> reliably causes Xorg to
hang at start-up, with the following message being printed to Xorg.0.log:
systemd-logind: failed to take device /dev/dri/card0: Did not receive a reply.
Possible causes include: the remote application did not send a reply, the
message bus security policy blocked the reply, the reply timeout expired, or
the network connection was broken.
If I boot to a console then run startx, Xorg prints a few standard messages,
then the console freezes - the screen does not turn black or change video
modes. CTRL-C, CTRL-ALT-DELETE, and CTRL-ALT-F2 do not respond. However, ACPI
hot-keys do seem to respond - hitting the power button causes Ubuntu to attempt
to shut down, and the console prints shutdown messages when this happens.
However, the shutdown process hangs again before it finishes shutting down - it
typically gets stuck when shutting down either the network or rng-tools.
The attached dmesg was produced by running the following script ... the
produced error.bz2 file was empty:
#!/bin/bash
startx &
sleep 10
dmesg > dmesg
cat /sys/class/drm/card0/error | bz2 > error.bz2</pre>
