Ubuntu hangs after connecting with cellphone

[Nuno Mota]

When trying to send a photo to ubuntu from a cellphone Ubuntu hangs, keyboard and mouse do not work an keyboard lights start flashing. This only happens when I'm notified that the connection was established.

I'm using a usb bluetooth adapter from sitecom and Ubuntu Hardy updated.

Please tell me what more information do you need to help fix this problem.

Does this happen after pairing or after attempting to transfer a file? I just made a report about my desktop crashing after pairing. I think i made a duplicate >.<

[Brad Johnson (kkhww1902)]

This happens to me as well. I believe it happens right at the beginning of the file transfer. I didn't notice my keyboard lights flashing, but the computer was definitely locked as my sound card started looping the buffer.

I was able to reproduce the 2 of 2 times I tried. I didn't see anything interesting in the logs after reboot.

I'm running 64 bit Hardy on Intel Core2 processor.

[kthxbai2u (kthx-codinggroundz)]

nope not same...

My computer hangs right after entering the passkey on the phone then the computer. the phone continues on with security question, and I accept the connection. This is when the computer hangs. Everything frozen!

If I establish the connection through Ubuntu instead of sending the file from the cellphone, and then using nautilus browse the cellphone files and copy them to the desktop everything works fine.

Does this happens with you too?

If necessary I'll post my dmesg output.

[kthxbai2u (kthx-codinggroundz)]

no. I mentioned it happens when pairing. to transfer files you must already be paired. yours is not the same either.

[Brad Johnson (kkhww1902)]

Is there anything we could easily do to find out where it is hanging?

[Torsten Schönebaum (torsten-schoenebaum-gmx)]

This happens to me as well: Ubuntu Hardy freezes just after pairing with my T610. The last lines in sylog are:

hcid[8380]: pin_code_request (sba=00:04:61:81:DD:58, dba=00:0E:07:45:7A:CF)

[Peter Hildebrandt (peter-hildebrandt)]

Got it, too. The order of events is:

1) Switch on Bluetooth on my Thinkpad X40 --> Bluetooth icon shows up
2) Intiate pairing from my cell phone (BenqSiemens EF81)
3) Confirm the passcode on the laptop
4) The new device shows up in the "trusted" list in the bluetooth preferences window
.... and in the very same moment a kernel panic occurs.

This is with Xubuntu 8.04 Hardy on a Thinkpad X40 (1.4Ghz P-M).

Nothing interesting in the logs. The syslog ends:

Interestingly everything works fine when I initiate the pairing from the laptop (tried in Ubuntu 8.04). Unfortunately XFCE does not have an option to initiate pairing.

I will be happy to contribute further information if needed.

I updated Hardy today. I noticed there were some kernel packages that were updated. I tried to connect my phone via bluetooth and this time it worked. Did the updates fix this problem for anyone else?

[Peter Hildebrandt (peter-hildebrandt)]

Well, sort of: Just tried it two times, and got a kernel panic both times, right after I enter the pass code on the laptop and the "Bonding established" popup notification showed up :-(

However, after a reboot the phone is now in the list of bonded devices and I can send data from the laptop to the phone.

It does not work the other way, from the phone to the laptop, though.

I would not consider this "fixed".

Peter

[Torsten Schönebaum (torsten-schoenebaum-gmx)]

No change here: Hardy still freezes just after pairing, regardless of which device I use to initiate the pairing. Some times the device shows up in the list of bonded devices after reboot, some times not.

[kthxbai2u (kthx-codinggroundz)]

Whoa i been posting in this bug as if it were mine... They are similair, im not sure if the guy meant he was transfering files when it crashed or he was intending to transfer files but never got to because of the crash.

[clovepower (mzattera)]

I've same issue: Asus Aspire 5520 laptop hangs right after pairing and keyboard light blinks.

I'm running 8.04.1 AMD64 and I've system updated to latest.

This happens with a Silicon Wave USB bluetotth adapter (I think it has a Broadcom 2035 chipset, not sure).

I can provide any info you need for debugging the issue, thanks.

[Brad Johnson (kkhww1902)]

This seems to be fixed for me in 9.04.
