[Lenovo ThinkPad X201 3626] Bluetooth re-enabled after resume from hibernation

[Jeffery To]

I'm currently running Raring x64 with the 3.8.0-19 Linux image on a Thinkpad x201. I have hibernation enabled by following the instructions in the official documentation[1].

If Bluetooth is disabled before hibernation, on resume it will be re-enabled. I have to manually disable it again in System Settings (where it still thinks Bluetooth is off, so I need to toggle the switch to on and then off again).

linrunner did some testing[2] and found that this appears to be a regression in the 3.8 kernel (possibly in the thinkpad_acpi module).

Please let me know if more information is needed - thanks!

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.10 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'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Jeffery To (jefferyto)]

Tested with the latest mainline kernel; bug has not been fixed.

Additionally, after resuming from hibernate and turning off Bluetooth (through System Settings), I'm no longer able to turn Bluetooth on (it flips to on then immediately off). Not sure if this is related.

[Jeffery To (jefferyto)]

To clarify, the "no longer able to turn Bluetooth on" issue affects the 3.10 kernel only.

[penalvch (penalvch)]

Jeffrey To, as per http://support.lenovo.com/en_US/downloads/default.page? an update is available for your BIOS (140-1.15). If you update to this, does it change anything?

If not, 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.

[Jeffery To (jefferyto)]

I've installed the latest BIOS and the situation is unchanged.

Regarding the terminal command, this is the output:

6QET70WW (1.40 )
10/11/2012

According to the BIOS changelog (http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS013909), this was an embedded controller update that improves the battery charge algorithms, so I wouldn't expect it to affect the Bluetooth module. (My BIOS was already at 1.40 when I submitted the initial bug report.)

FWIW, on boot the Bluetooth LED is on, then goes off while on the initial ThinkPad screen. On the GRUB menu, the LED is still off. When it times out and the kernel continues to load, it's then that the LED comes back on again.

[penalvch (penalvch)]

Jeffery To, thanks for reflashing your BIOS. Could you please test the newest mainline kernel available via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc1-saucy/ and report the results?

[Jeffery To (jefferyto)]

I've tried the v3.11-rc1-saucy and v3.11-rc2-saucy kernels; the results were the same as the v3.10 kernel I tested earlier.

[penalvch (penalvch)]

Jeffery To, thank you for testing the newest mainline kernel. Did this problem not occur in a release prior to Raring?

[Jeffery To (jefferyto)]

I don't recall having this problem with Quantal. Also, as noted in the original report, linrunner did some testing and found this to be a regression in the 3.8 kernel.

[penalvch (penalvch)]

Jeffrey To, the next step is to perform a bisect between Quantal and Raring, to identify the commit that caused this problem. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

[Jeffery To (jefferyto)]

I had to bisect the mainline kernel, since the Ubuntu kernel skipped 3.6 (the issue was in every 3.7 kernel I tried). The result:

Jeffrey To, thank you for bisecting. Could you please test the latest mainline kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc3-saucy/ ?

[Jeffery To (jefferyto)]

I've tested rc3; the issue still exists.

[penalvch (penalvch)]

Jeffery To, the issue you are reporting is an upstream one. Could you please report this problem through the appropriate channel by following the instructions _verbatim_ at https://wiki.ubuntu.com/Bugs/Upstream/kernel#KernelTeam.2BAC8-KernelTeamBugPolicies.Overview_on_Reporting_Bugs_Upstream ?

Thank you for your understanding.

Hello,

I'm currently on the 3.8.0 kernel with Ubuntu 13.04 (Raring) x64 on a
Thinkpad x201. I have hibernation enabled by following the instructions in
the official Ubuntu documentation[1].

If Bluetooth is disabled before hibernation, on resume it will be
re-enabled.

I have the latest BIOS installed (1.40-1.15)[2], and can reproduce this
issue with the latest mainline kernel available to me (v3.11-rc3-saucy)[3].
I didn't experience this issue with the 3.5.0 kernel (with Ubuntu 12.10
Quantal), so it appears to be a regression.

I've done a bisection with this result:
