I'll take a first look.

Walter - Some questions for investigation:

1. Can you find out if this happening on 1.3? That will confirm if this is a regression or not.
2. This is a JB-specific bluetooth bug also, right?
3. Can you confirm this on 1.4 & get a crash report with this bug?

Nexus 4 is using bluedroid stack, and we officially support bluedroid stack for 1.4.
We currently support two bluetooth stacks for JB. All shipping devices currently use bluez as back-end.

1. It's different backend stack for 1.3 (bluez) and nexus is using (bluedroid)
2. Let's say bluedroid specific bug
3. I think there is no official build of 1.4 nexus now. I will try to confirm later

Comment 5

[Jason Smith [:jsmith]]

So if this is officially supported for 1.4, then should this be nomed to block for 1.4?

I think it's reasonable to nominate to blocker of 1.4.

Can you help to figure out the concrete reproducing steps?
I tried gaia=c250da9f, gecko=a742504b, i fail to reproduce the crash. I will increase REPS anyway, it will be good if you can help to test.

Comment 8

[Shawn Huang [:shawnjohnjr][:shuang] (as a happy gecko contributor)]

Hello Dietrich,
Is it 100% reproducible? Can you provide more information such as back trace?

Comment 9

[Eric Chang [:ericcc] [:echang]]

About 10 times I tested, the phone restarted once with build of 17(jenkins-B2G.master.nexus4-264)

1. Nexus pairs up with a Mac.
2. Nexus sends a file to Mac.
3. Transfer completed, then Nexus restarted, and the icons on home screen overlapped. But not sure if it is the same as described in this bug.
4. but not reproducible all the time; Try with Ubuntu, but not able to reproduce.

I tried over 20 times with MacOSX 10.8.5, not be able to reproduce it. I'm not sure that is easier to reproduce on MacOSX 10.9. I will try it later.
Can you provide minidump and exact crashreporter symbol version?

Comment 11

[Eric Chang [:ericcc] [:echang]]

That time my phone crashes which is right after the file transfer has been completed, the build is from TWCI #264, but according to Shawn, the symbol is not matching again the dump. I will try reproduce again.

But so far, I was not able to reproduce this issue as described in this bug.

Hi Dietrich,
Do you have more information on this? adb logcat or any other info to help? Rate to reproduce? Nexus build from PVT or by yourself? Thanks.

Comment 12

[Dietrich Ayala (:dietrich)]

This time I hit issues getting the devices to pair, but didn't get the crash.

NOTE: I'm flashing between tests to ensure a clean environment.

Comment 13

[Shawn Huang [:shawnjohnjr][:shuang] (as a happy gecko contributor)]

I will have further update if i have backtrace.

Comment 14

[Eric Chang [:ericcc] [:echang]]

Thanks, I tried like 30 times yesterday, with Mac 10.9.2, 10.9.0and ubuntu 12.4, pairing, file transfer, multiple file transfer, unpairing, my nexus works okay without crash.

Hi Eric, are you using Eng or User/Userdebug build?

Comment 16

[Eric Chang [:ericcc] [:echang]]

I am using engineering build here.

We have identified one MOZ_ASSERT in bug 983590 while during with gecko debug build, i suspect this bug is also related to the fallout of bug 967364 which been mentioned in bug 983590.  But all this is just suspicion.
