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 v4.16 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.

The behavior appears to be much better with the kernel version 4.16-rc6. However, I think this is not 100% solved, as the following error is still (but now rarely) happening when disconnecting from a network:

[ 5934.740004] ath10k_pci 0000:02:00.0: failed to install key for vdev 0 peer xx:xx:xx:xx:xx:xx: -110
[ 5934.740010] wlp2s0: failed to remove key (0, xx:xx:xx:xx:xx:xx) from hardware (-110)

With that MAC address being from the router. I believe this error, when happening on shutdown or reboot, is the source of the problem, as when that messages are not shown (apparently) the error doesn't happens.

Looks like the ath10k_pci device drops off the PCI bus completely. I guess you can't find the device in `lspci` when this happens.

Does the device re-appear if you rescan the PCI bus? i.e. `# echo 1 > /sys/bus/pci/rescan`.

This is not happening with the kernel 4.16-rc6, so I added the tag kernel-fixed-upstream.

I can no longer boot with the 4.15.0-12 kernel successfully when the error happens, it just freeze and I wait until the HD stops to shutdown it by keeping the power button pressed. I was lucky the system was able to boot and I could obtain some information from the error.

Definitively, with the kernel 4.15.0-12 (and previous versions), it has a pattern of:

Work -> Don't work -> Work -> Don't work

Frequently causing a freeze (kernel panic?). One curious thing I noticed is that it freezes always in the same line on the boot:

Started Load/Save Screen Backlight Brightness of backlight:intel_backlight.

I don't know why, but it's always on this line.

It's hard to say which commit(s) fixes the issue, so the fastest way is to bisect locally.

You can still follow the steps [1], but instead of "bad good", use "old new":

$ git bisect start
$ git bisect old v4.16-rc4
$ git bisect new v4.16-rc5
$ make localmodconfig
$ make -j`nproc` deb-pkg
Install the newly built kernel.
If the issue still happens,
$ git bisect old
Otherwise,
$ git bisect new

Bluetooth: btusb: Use DMI matching for QCA reset_resume quirking

    Commit 61f5acea8737 ("Bluetooth: btusb: Restore QCA Rome suspend/resume fix
    with a "rewritten" version") applied the USB_QUIRK_RESET_RESUME to all QCA
    USB Bluetooth modules. But it turns out that the resume problems are not
    caused by the QCA Rome chipset, on most platforms it resumes fine. The
    resume problems are actually a platform problem (likely the platform
    cutting all power when suspended).

    The USB_QUIRK_RESET_RESUME quirk also disables runtime suspend, so by
    matching on usb-ids, we're causing all boards with these chips to use extra
    power, to fix resume problems which only happen on some boards.

This commit fixes this by applying the quirk based on DMI matching instead
of on usb-ids, so that we match the platform and not the chipset.

Here is the /sys/kernel/debug/usb/devices for the Bluetooth module:

Because the commit you bisected has been included since 4.15.12, which you said the issue is not fixed (comment #10).

That particular commit will be included in next Bionic kernel update.

So I guess now the bug is "waiting for /dev/disk"?

The bug is still the same. What happened was that the system froze at a different message in that particular try. Journalctl from a successful initialization showing the most common point of failure:

systemd[1]: Starting Load/Save Screen Backlight Brightness of backlight:intel_backlight...
systemd[1]: Started Load/Save Screen Backlight Brightness of backlight:intel_backlight.
systemd[1]: Started Uncomplicated firewall.

systemd[1]: Listening on Load/Save RF Kill Switch Status /dev/rfkill Watch.
systemd[1]: Starting Load/Save RF Kill Switch Status...

The messages after the one of intel backlight are the ones related with /dev/rfkill. This is why it freezes showing:

[ OK ]: Started Load/Save Screen Backlight Brightness of backlight:intel_backlight.

Probably the RF Kill has a serious enough failure when this bug happens that the entire system freezes.

This is funny, but the option btusb.enable_autosuspend=0 make the bug happen on v4.16-rc7. I'm seeing a pattern that, when I change the kernel version or a grub option, I can't just turn on and off the notebook twice (as it triggers normally), but thrice.

So, every time I change a configuration I have to turn the notebook on and off thrice to test.

The good new is that btusb.enable_autosuspend=0 triggers the bug.

And no v4.15 kernel from mainline is free from this bug.

This bug is biting me for a long time and was being very hard to find, but finally it is cornered.

Unfortunately, this kernel still has the same issue.

The parameter btusb.enable_autosuspend is decisive to define if the fixed kernels will work. Disabling it ("btusb.enable_autosuspend=0") makes the fixed kernels act like the broken ones. However, setting it in broken kernels ("btusb.enable_autosuspend=1") has no effect.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
