Since migrating to ubuntu 17.10 I have had some issues with suspending my system (Dell XPS15 with nvidia / intel dual graphic card)

When I press the power button briefly or call systemctl suspend, I can see that the system tries to go in suspended mode but it comes back on after a few seconds. Extracts from the syslog below 

[ 2968.230422] PM: Suspending system (mem)
[ 2968.230485] Suspending console(s) (use no_console_suspend to debug)

And according to lspci

3e:00.0 USB controller: Intel Corporation DSL6340 USB 3.1 Controller [Alpine Ridge] (rev ff)

Running the stock Ubuntu kernel. No special tweak

Anybody facing the same issue with a way to resolve this ?

I´ve had similar issues on my Ubuntu 17.10 and upgrading BIOS to latest has fixed problems (tested mostly 1.5.1 and a little bit 1.6.1).

I had similar problem. The system won't shutdown after upgrade to 17.10. I shifted to earlier stable version of kernel from grub at startup, and now everything works fine. I am currently using 4.10.0-37-generic and was facing problems on 4.13.0-16-generic

I'm facing the exact same issue on 17.04, also with an XPS 15. Disabling the USB device 'fixes' it - or at least allows you to suspend.

You can unbind the USB device with the command (using answers from here and here)

echo "0000:3e:00.0" | sudo tee --append /sys/bus/pci/drivers/xhci_hcd/unbind

I have the same issue with a Dell XPS 15 9550 (also with both Nvidia and Intel graphics) running Ubuntu 17.10. I get the same lines in syslog:

[23886.943531] suspend_common(): xhci_pci_suspend+0x0/0xd0 returns -110
[23886.943536] pci_pm_suspend(): hcd_pci_suspend+0x0/0x30 returns -110
[23886.943542] dpm_run_callback(): pci_pm_suspend+0x0/0x130 returns -110
[23886.943546] PM: Device 0000:3e:00.0 failed to suspend async: error -110
[23887.443502] thunderbolt 0000:08:00.0: Ignoring mailbox command error (-110) in icm_suspend
[23887.443583] PM: Some devices failed to suspend, or early wake event detected

I don't understand why (found here), but I can resolve the issue by uninstalling the intel-microcode package with apt (or you can go to the "Software & Updates" application, navigate to the "Additional Drivers" tab, and select "Do not use this device"):

Software & Updates

When I remove intel-microcode and reboot, the problem seems to go away, and I can suspend like normal.

EDIT: BTW I am on the most recent BIOS version 1.6.1.

EDIT2: From some recent updates (I believe) it seems as though selecting "Do not use the device" is no longer an option for microcode. I am now on BIOS 1.6.1 (after Dell cancelled 1.6.1 and then re released it later), and the suspend issue seems to still be around... :(
