The symptom sounds different from boo#955096. That bug was about the blockage of shutdown/reboot while yours is spurious wakeup after shutdown. This is mostly due to either ACPI or XHCI wakeup.

Check /proc/acpi/wakeup. For each "enabled" item, echo the device name, e.g. if "USB1" shows "enabled", run like echo -n USB1 > /proc/acpi/wakeup Then this item will be disabled. After disabling all, try to shutdown and check whether the reboot happens.

Disabling the ACPI wakeup would also disable the wake up after suspend, of course. It's just for figuring out the cause.

Another possible spurious wakeup source is USB. XHCI driver has various workarounds for such firmware problems. You can pass quirks option to xhci-hcd module, e.g. try to pass "xhci_hcd.quirks=0x42000" boot option.

I have disabled all enabled processes in /proc/acpi/wakeup as you suggested but there is just no result. The laptop reboots everytime independently if it is running on battery or on power supply; Also I have entirely disabled Wake on USB from UEFI. -- You are receiving this mail because: You are on the CC list for the bug.

Did you try to boot with xhci_hcd.quirk option I suggested?

Note that you can edit the boot option directory in GRUB by pressing 'e' key.

And do I understand correctly that your machine *reboots* after shutdown automagically?

For a spurious reboot, another possible source is Wake-on-LAN. This can be disabled via ethtool command on the fly.

Yes, it reboots automatically. I have disabled Wake On LAN from UEFI too - there was no effect. I will try this parameter in GRUB directly and will report later. -- You are receiving this mail because: You are on the CC list for the bug.

We have HP 4540s here, and they were fine, AFAIK. Just to be sure, check the current value of xhci_hcd.quirks % cat /sys/module/xhci_hcd/parameters/quirks -- You are receiving this mail because: You are on the CC list for the bug.

I remembered that there were few times when after login the network manager showed no connections and the checkbox for enabling the Wi-Fi was inactive. I decided to turn off the Wi-Fi before shutdown the machine. The result was a normal shutdown without the restart (tried several times!). But on the next login the situation with the network manager was the same - no option for connectivity. I am one of the lucky owners of ProBook 4540s. But I am from the most "lucky" ones who own a machine with RaLink RT3290 in it. This adapter gave me a lot of headaches before. Now it showed its 'evil' again. I have blacklisted the rt2800pci module in /etc/modprobe.d/50-blacklist.conf and now I'm using my external TP-Link TL-WN721N instead of it. Just had to restart NetworkManager.service and all was fine. Technically there is a workaround but issue is not resolved. I think that the problem is with rt2800pci driver which in fact was never the proper driver for this adapter and has never had a full support for it (the Bluetooth part is not working at all). It seems to me that it has a problem to apply a proper power management to the adapter or it is someway broken and causes the problem. Just to notice that until recently I have used Fedora 23 with rt2800pci enabled (which managed to work properly with the adapter as far as the more recent versions of the Linux kernel, without breaking the connectivity or failing to keep speed as in the earlier ones) and there was no problem. Nevertheless, thanks for the support and the spent time :) -- You are receiving this mail because: You are on the CC list for the bug.
