Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.1 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

This is a completely new laptop so haven't tested any previous kernel versions. I need at least kernel 3.17 for MST support for my docking station so therefore Ubuntu 15.04 was the only option for me with kernel 3.19 as default.

I just tried both 4.1.0 and 4.1.1 and the bug is still there. The last message I see when I turn off the laptop is "Reboot: Power down" or something like that, and then it reboots.

No change after BIOS upgrade.

"If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date"

@Christopher M. Penalver What do you mean with "[...] could you please both specify what happened [...]"?

Christoffer Holmstedt, could you please test the latest mainline kernel (4.2-rc1) and advise to the results?

I'm now back in front of the failing computer and have tried 4.2rc1 - rc4 and they all fail in kernel panic during boot up. "BUG: unable to handle kernel paging request at fffffffffffffd8". Due to this I'm unable to verify if the new kernel versions solves this problem at the moment. Any suggestions on how to proceed are appreciated (or just wait for 4.2 final?).

Has anyone tried this workaraound: Disable "Wake On LAN" or "Wake On WLAN" in the BIOS.
I think it solved my problem although I'm not certain yet.

If this works, it may expose the original flaw or at least point the debuggers in the general direction.

@FatTony Thank you. Wake on LAN was actually enabled by default on my laptop as well. I have now turned it off as I don't need it and the system turns off properly.

PS. Strange that that a BIOS setting can affect Ubuntu in this manner and Windows is unaffected.

no longer affects:
