Bug Description

I am using Saucy in XMir mode with the standard Unity desktop on the Lenovo Thinkpad Twist.

When I suspend the system not only the suspend itself is broken (bug 1213233) but also after waking up I cannot use my Bluetooth devices any more (mouse, keyboard). I have to reboot to get Bluetooth back working.

Do not ask me to update the BIOS from 1.52 to 1.57, this leads to bug 1210748.

Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of the introduction of a regression, and when this regression was introduced. If this is a regression, we can perform a kernel bisect to identify the commit that introduced the problem.

This is independent whether the Unity desktop is run with XMir or normal X.

I did not use Suspend for very long time, can even be the first time for me with Saucy on this machine.

Sometimes, the Bluetooth devices, sometime only one of them, work again after suspend, but in most cases they are dead.

Would it be possible for you to test some earlier kernels, to see if this is a regression? It might be good to start with the 3.8, 3.9 and 3.10 kernels:

v3.8: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-raring/
v3.9: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-raring/
v3.10: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.10-saucy/

You don't have to perform a re-install, you can install these kernels on top of your existing installation, then select them from the GRUB menu during boot.

I get the problem only with the 3.11.x kernel. All the old (3.10.x and earlier) kernels are OK.

Joseph Salisbury (jsalisbury) wrote :

Thanks for testing, Till.

I'd next try to identify which 3.11 release candidate introduced the regression.

Can you test the following kernels and report back? We are looking for the earliest kernel version that exhibits this bug:

v3.11-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc1-saucy
v3.11-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc2-saucy
v3.11-rc3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc3-saucy/
v3.11-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc4-saucy/

You don't have to test every kernel, just up until the kernel that first has this bug.

Thanks in advance!

Since I have tried the kernels 3.8, 3.9, and 3.10 yesterday, I am not able to reproduce the bug any more, even not with the current Ubuntu kernel (3.11.0-3-generic) and the previous one (3.11.0-2-generic). Also the problem of suspend automatically waking up immediately again (bug 1213233) does not occur any more.

All tests done in XMir mode.

Ok, thanks for the update, Till. I'll keep this bug as incomplete for now. Please move it back to confirmed if the bug starts to happen again.

Hi all,

I just hit the same problem, and I've managed to fix it for my case (Dell E6430 laptop with integrated bluetooth).

I've had exactly the same experience as Till, in that 3.11 caused bt to no longer work after a suspend/resume for me. I'm surprised to hear that the problem has magically gone away for Till, as there is a very real reason causing it in the form of a "fix" in 3.11 .

I've written a patch for this (reverting the fix) and send it upstream. I'll also attach it here.

Regards,

Hans

Also have this problem running Ubuntu 13.10 kernel 3.11.0-12-generic on Lenovo X1 Carbon and Microsoft BT mouse 5000. Never had an issue before with this hardware.
Also noticed, when resuming from suspend and opening the bluetooth dialog, I tried to turn bluetooth off and on again. The dialog will not re-enable bluetooth (it goes on and switches off by itself immediately). Reboot did not resolve it, had to do a full shutdown and then turn back on to get bluetooth working again.

I did some testing with the 13.10 release version:
Kernel 3.10: works fine
Kernel 3.11-rc1: fails

I marked the bug as confirmed as per Joseph's instructions.

I've seen similar bug reports on other distros, it seems something got broken in kernel 3.11.

I am suffering from this bug too, could you introduce a fix as soon as possible. It is highly lowering the usability of the system. After resume I had to restart, because bluetooth doesn't work and and network doesn't work either, because of this bug https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1184262.

@Hans, thanks for the patch. However, I don't see the patch in the mainline tree as of yet. Do you happen to know the SHA1 for the commit in mainline?

Hans de Goede (j-w-r-degoede) wrote :

@Joseph,

I'm sorry I was wrong it is not upstream yet. I was on the wrong git branch when I checked. It has been accepted into bluetooth.git:
http://git.kernel.org/cgit/linux/kernel/git/bluetooth/bluetooth.git

But it has not found its way into Linus' tree yet.

Regards,

Hans

@Hans, any way to apply the patch without waiting for kernel 3.12 or compiling the entire kernel?

Till Kamppeter, as per http://download.lenovo.com/express/ddfm.html an update is available for your BIOS (1.63). Via 1.58, this version would have an internal mouse fix for 1.57 . If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything regarding bluetooth suspension? 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

Thank you for your understanding.

Christopher, this bug is not specific to the Lenovo ThinkPad Twist. In this bug report it affects users on a Lenovo X1 Carbon, two different Dell laptops, and in my case an HP Folio 13. There are also similar bug reports in other distros that point to a regression in the 3.11 kernel.

I've been having this issue also. After a conversation in #ubuntu on IRC, someone pointed out a script for /etc/pm/sleep.d

The script as shown below seems to have fixed this issue, although it is (at least to me) a workaround.

Thanks
