["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Ruokoton, could you please confirm this issue exists with the latest
development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
could you please run the following command in the development release
from a Terminal (Applications->Accessories->Terminal), as it will
automatically gather and attach updated debug information to this
report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

  Bus 004 Device 002: ID 0a5c:201e Broadcom Corp. IBM Integrated Bluetooth IV

  All bluetooth connections seem to stall after certain period of time
  (seen from dmesg) - this alone makes file transfers, etc impossible,
  although there might be other problems too.

  Recv failed: Software caused connection abort

  dmesg:
  [ 5787.352443] Bluetooth: hci0 link tx timeout
  [ 5787.352453] Bluetooth: hci0 killing stalled connection D4:88:90:C2:8B:33

  The connection will always stall after 10 rounds. The pinged device is
  Samsung Galaxy S phone. When the same is being pinged from another
  computer, also running Ubuntu, the connection stays stable until
  aborted.

  Noticed exactly similar behavior reported here:
  https://bbs.archlinux.org/viewtopic.php?id=120488 - only common things
  are bluez and Broadcom bluetooth chip.
