I upgraded from Ubtuntu 17.04 to Ubuntu 17.10 and this bug started appearing (didn't have this with the versions before).
When I lock my screen on my Lenovo T450s and the notebook sits in the dock (two external screens attached), one of the three things happen when I come back after some time and try to unlock (so it went to power safe inbetween):
* Most of the time the computer was just shut down and I have to start it again
* Sometimes the notebook screen flickers weirdly and one of the two other screens show pixel garbage
* The notebook screen shows the lock screen but is completely frozen.
Occasionally unlocking also works.
The last thing I find in /var/log/syslog is
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun
Note: Ubuntu uses kernel version 4.13.0-16-lowlatency for some reason, but the issue also appears when I boot with the generic version.
I reported already here, but was advised to create a new bug:

What happens is after I dock my laptop, lock it via clicking the lock icon, and wait ~30 minutes, one of the following three things happen ~50% of the time when I come back to unlock it:
* Most of the time the computer is found shut down.
* Sometimes the notebook screen flickers weirdly and one of the two external monitors show pixelation.
* The notebook screen shows the lock screen but is completely frozen. Occasionally unlocking works.
I have two external monitors attached to the docking station.
When I dock my laptop, the battery indicator does recognize its charging.
I've not seen this issue when:
1) With the laptop in the dock, while actively using the laptop.
2) With the laptop out of the dock and no external monitors present.
This bug started after upgrading from Ubtuntu 17.04 to Ubuntu 17.10.
Using or not using the following kernel parameter didn't change anything:
i915.enable_rc6=0
PC temperatures are normal as per lm-sensors.

What happens is after I dock my laptop into a Lenovo ThinkPad Ultra Dock Type 40A2 20V, lock it via clicking the lock icon, and wait ~30 minutes, one of the following three things happen ~50% of the time when I come back to unlock it:
* Most of the time the computer is found shut down.
* Sometimes the notebook screen flickers weirdly and one of the two external monitors show pixelation.
* The notebook screen shows the lock screen but is completely frozen. Occasionally unlocking works.
I have two external monitors attached to the docking station.
When I dock my laptop, the battery indicator does recognize its charging.
I've not seen this issue when:
1) With the laptop in the dock, while actively using the laptop.
2) With the laptop out of the dock and no external monitors present.
This bug started after upgrading from Ubtuntu 17.04 to Ubuntu 17.10.
Using or not using the following kernel parameter didn't change anything:
i915.enable_rc6=0
Updated docking station firmware to latest 2.33.00.
PC temperatures are normal as per lm-sensors.
