I have a series of symptoms of horrid problems with this laptop, so I am going to mention more of them in case they're related. Whenever I undock the laptop from my ultradock, unity-sessions-daemon crashes and either then or some other time, my swap space accumulates 1.2 GB or so of use, even though I have 20GB of RAM and it is mostly not in use. After, this various other things often don't work and I have to reboot, which leads to the problems filed above.
For instance, right now the swap still shows some usage, which it shouldn't, and choosing to shut down the computer from the taskbar does nothing. Syslog looks like this, when I tried to shut down twice starting at 10:15: auth.log: Apr 22 10:15:40 cpbl-t450s CRON[28881]: pam_unix(cron:session): session closed for user meuser Apr 22 10:16:02 cpbl-t450s systemd-logind[29988]: System is powering down. syslog: Apr 22 10:15:52 cpbl-t450s kernel: [ 5762.175096] [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

Instead, it hangs on "Reached target shutdown". (See image) Along the way, I believe there is briefly a full page of "drm:gen8_irq_handler [i915] *ERROR* The master control interrupt lied (SDE)!" messages. If I leave it there for a long time (> 10 minutes?) it does/may actually turn off without me forcing it off, but this makes no difference to the subsequent behaviour. Moreover, if I press Ctrl- Alt-Del fast, many times, I get the "Rebooting immediately" message, but it doesn't. When I try to boot, I experience the following. It requires at least two reboots to be able to log in: On the first boot, the Grub page is skipped, and it hangs on the Ubuntu logo with moving dots. Eventually, I reboot it. The second time (this is all reproducible), it boots but very slowly. It stalls at "britty.service" and eventually gives me a message about dev-disk-by , where it waits for 90 seconds before booting. After that, things proceed to a normal login screen. Behaviour after that is sometimes normal. This is a 1 month-old computer.
