Bug Description

Bose QC35 with latest firmware
Ubuntu 17.10

This is a regression from 17.04 Ubuntu Gnome. In 17.04, you had to temporarily disable `le` mode to pair but after pairing, everything worked flawlessly. In 17.10, pairing works out of the box, but the following issue appears:

After a few hours of being connected, the connection between bose qc35 and Ubuntu seemingly breaks: the headphones don't play any sound anymore. re-pairing fails and restarting the headphones doesn't fix the issue. It seems bluetoothd crashed conmpletely since `bluetoothctl` doesn't work anymore.. Restarting Ubuntu fixes the issue.

syslog contains a bunch of kernel stacktraces including a nullpointer dereference..

@Merlijn

Hey, a few follow-up questions:

1. Are you using bluez as a snap on desktop?
2. What s the kernel version being used, you can check this with $ uname -a

Thanks,
KZ

It's not bluetoothd (BlueZ) crashing. The log information shows the kernel crashing in 'bluetooth' which is a kernel module. This will of course cause bluetoothd to stop working properly, but the bug is not in bluetoothd, it's in the kernel.

Please try a slightly older kernel or two from here:

Since you say Ubuntu 17.04 worked, try kernels down to v4.10 (which is where it was working).

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.14 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.

@joseph

I have not found a reliable way to replicate this bug so I cannot test if it is still present in the latest upstream kernel.

I have attached the full syslog of multiple days + multiple crashes in the second message in this thread. Does it give any hints as to how to replicate this issue?

My computer (Depp Precision 5510 with Ubuntu 17.10 - actually Pop!_OS - fresh install) is affected by the same kind of bug.

Connection to bluetooth speakers sometimes works, sometimes does not, sometimes works well at boot then stops. I am not able to reproduce the issue consistently. When bluetooth stops working, it can not be desactivated/reactivated from panel, system settings stalls, shutdown fails => hard reset.

What information should I provide ?
I have this :

axel@pop-os:~$ dmesg |grep -i bluetooth
