I have noticed that after I have used VirtualBox, I cannot suspend my computer. It enters a suspend state, but after a couple of seconds it wakes up again. Only a reboot has been able to solve the problem. I tried killing all processes related to VirtualBox (so that pgrep VBox shows nothing), and also removing the corresponding kernel module (rmmod vboxdrv etc), but the problem did not go away.
I'm using VirtualBox 5.2.12 r122591 installed from virtualbox.org and Kubuntu 16.04.
Edit: I have my virtual HDD on an external USB drive, and after more troubleshooting I just noticed that it is only if after running VBox I disconnect the USB drive that the problem appears. If I reconnect the drive, I can suspend again.
Here is what dmesg says around the time I tried but failed to suspend, without the external USB disk plugged in. Perhaps that "usb4-port2: cannot disable (err = -32)" is a hint? Indeed, with the drive plugged in and suspending successfully, that error message is not present.
