[Anthony Wong (anthonywong)]

Tim, can you do an update and test with the 2.6.38-10.46 kernel again?

[TienFu Chen (ctf)]

Bug remains with 2.6.38-10.46 kernel.
This bug won't be reproduced in every tries, but should be reproduced in 5 times of retries.

[Keng-Yu Lin (lexical)]

Installed the daily Oneiric daily build (20110728), the issue is fixed in Oneiric.

[Ara Pulido (ara)]

Keng-Yü, is this a bug in bluez, linux or both packages?

[Keng-Yu Lin (lexical)]

@Ara, I am not sure at the time, still working on finding the cause.

[Keng-Yu Lin (lexical)]

The bug can be fixed in bluez. I am forming a patch.

[Keng-Yu Lin (lexical)]

Since the issue is not found in Oneiric and this is blocking certification of Natty, it should make sense to get the attach patch through SRU for Natty.

The patch is very straightforward, just adds some retries and sleep in-between on initialising the bluetooth device.

[Robert Ancell (robert-ancell)]

Reviewed the patch and uploaded to natty-proposed. The patch seems simple and low risk, as Keng-Yü says it just retries bringing the device up if it doesn't occur fast enough.

[Clint Byrum (clint-fewbar)]

Hello Tim, or anyone else affected,

Accepted bluez into natty-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Keng-Yu Lin (lexical)]

I tested the bluez package in -proposed on Asus 1215p and confirmed the it works.

[Ara Pulido (ara)]

Did this package make it to -updates?
Can we put it as Fix Released?

[Anthony Wong (anthonywong)]

Ara, I still don't see it in natty-updates. :(

[Jesse Sung (wenchien)]

On some machines, it seems that usb hubs do not get power while
being suspended. We can get something like this in dmesg:
     usb usb2: root hub lost power or was reset

When this is the case, .reset_resume is called instead of .resume.
If .reset_resume is not set, bluetooth modules would stay in an unusable
state because the resume function is not called.

Hi Oliver,

Humm... You're right, there is an unplug-replug cycle, but bluetooth
doesn't work until I restart bluetoothd. If the resume function is
called through .reset_resume, then bluetooth works right after resume.

Regards,
Jesse

Hi Oliver,

Indeed, loss of power event should not be ignored.

Just tested file transferring. If there's no active connection,
everything goes fine. But if a file is transferring while going to S3,
bluetooth is not working after resume. Use applet to disable and
re-enable bluetooth makes it work again...

Wondering what is the right way to handle loss of power...

Regards,
Jesse

Finally Bluetooth does not turn on after turning it off manually (13.10 was a problem with this), but the icon of Bluetooth still disappears. Can create bug report for trusty?
