USB bluetooth device floods errors to syslog

Can you attach your entire dmesg output after you see the syslog getting flodded with messages? Thanks.

Also, the Hardy Heron kernel was recently uploaded for testing. We'd really appreciate it if you could try testing with this newer kernel and verify if this issue still exists. Unfortunately, the Hardy Heron Alpha1 LiveCD was released with the older 2.6.22 kernel. You'll have to manually install the newer Hardy Heron kernel in order to test. This should not be the case for Alpha2 which is set to come out around Dec 20. However, here are the instructions to install if you choose to do so, otherwise just wait for Alpha2 to come out:

1) edit the file /etc/apt/sources.list and add the following line:

deb http://archive.ubuntu.com/ubuntu hardy main restricted

2) sudo apt-get update
3) sudo apt-get install linux-image-2.6.24-1-generic
4) reboot and select the new kernel from the grub menu

After you've tested, please feel free to revert back - ie boot into the old kernel, sudo apt-get remove linux-image-2.6.24-1-generic, and remove the line from /etc/apt/sources.list . Please update this report with your results. Thanks in advance!

Sorry Ossi, I think my english wasn't quite clear. Can you attach the entire dmesg output? It should include the entire boot log of your machine as well as the errors you are seeing. It also might be helpful if you could attach the other files outlined here: https://wiki.ubuntu.com/KernelTeamBugPolicies . I'm also curious if you've tried the newer kernel? (No worries if you're waiting for Alpha2). Thanks!

Sorry I am a newbie with this bug reporting system. I try to provide all required information. dmesg.0 is generated by cat /var/log/dmesg.0 because original dmesg has its boot procedure overwritten because of errors from bluetooth dongle.

So there were no help from new kernel in Hardy. I found a suitable fix for this: In vanilla kernel source changing instance in file drivers/bluetooth/hci_usb.c does the trick.

Under comment

        /* RTX Telecom based adapters with buggy SCO support */

A new line is added:

        { USB_DEVICE(0x0e5e, 0x6622), .driver_info = HCI_BROKEN_ISOC },

I hope this helps.

Hi Ossi,

Thanks for investigating and providing a solution. I'll reassign to the kernel team. Thanks!

I'm not sure if this should be filed separately, but I get a flood like this (with connection handle 1) on 2.6.24 (both Hardy kernel and vanilla), and no sound comes from the headset. On 2.6.22, it works fine.

This is with the chip with ID 0a5c:2101 (Broadcom BCM2045).

Brian - please start a separate bug report.

This bug was fixed in the package linux - 2.6.24-4.6
