If the patch series is not applied, after 6 months of raring there will be 6 more months of saucy without the possibility to use the bluetooth tethering facility (bluetooth DUN) offered by mobile phones. Sounds bad. In any case if this patch set is too extensive to apply, the obvious conclusion is that the not-too-extensive patch to apply is disabling rfcomm altogether in 3.8, 3.9, 3.10, 3.11. As is, rfcomm is totally broken, unusable and quite dangerous. It makes the kernel crash systematically at every use. Furthermore, the crash is due to kernel data being randomly rewritten with garbage, which means that the actual crash may happen *seconds to minutes after the actual issue provoking it* (seen 40 sec personally). It is a bad situation that can easily lead to severe data loss in addition to down time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1165433 Title: Kernel 3.8.x panics on bluetooth DUN disconnect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165433/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1165433] Re: Kernel 3.8.x panics on bluetooth DUN disconnect
Tested 3.10.2 from the mainline ppa (in spite of the bad experience with
3.9.8 that is broken).
The linux bluetooth screen of death is still there, 127 days since first
notification on the LKML for a fully reproducible regression that
completely impairs a subsystem and causes a hard kernel crash with a
disastrous memory corruption, sigh.
Specifically, the RFCOMM session disconnection fixes that got applied to
Linux 3.10 commits (8 off) 24fd642ccb24c8b5732d7d7b5e98277507860b2a to
fea7b02fbf73adb2e746f00ed279a782de7e74e4 do not help.
All LKML activity on this stopped on 2013-06-25. From it it looks like
kernel developers seem to believe that to reproduce the bug a hard power
down of the remote is necessary ('Yes. With power down I meant a hard
power down, such that the remote doesn't has the chance to close the
session cleanly.'). Looks like this is not the case. A simple bluetooth
DUN activation / deactivation cycle from network manager (targeting a
Galaxy S mobile phone that is never switched off) seems to trigger the
bug and the kernel crash here. They may also thik that the bug is fixed
with the latest RFCOMM session disconnection fixes or that at least it
is reduced in scope (so that only a process is killed and a TTY not
released, without the disastrous memory corruption in the kernel).
Either here we are discussing a completely different bug from that in
the LKML thread http://news.gmane.org/find-
root.php?message_id=%3c519480A1.6030909%40ahsoftware.de%3e or the kernel
developers miss some relevant information.
Can someone from the ubuntu kernel team forward this info to Alexander
Holler and others on the LKML list revitalizing the thread?
In the meantime, may I again suggest unconfiguring RFCOMM TTY support
from ubuntu production kernels as a SRU until this is fixed, so DUN
still remains unfunctional, but at least the kernel crashes that may
lead to data loss are prevented? The thread on LKML does not exclude
data loss '[crash reports] don't make much sense because they happen
because of a disastreous memory corruption, which means the BUGs can
include almost everything (hopefully nothing which eats your disk
contents).'

Looks very likely. But also bad, since rfcomm is among the top users of this and linux BT people knew there was something wrong since http://marc.info/?l=linux-bluetoothm=136386669411447w=2, with more info in http://marc.info/?l=linux-bluetoothm=136537407411019w=2, or maybe even earlier, e.g. http://marc.info/?l=linux- bluetoothm=136363425514280w=2.

Here's another way to trigger the crash: 1. Set up and use rfcomm/btusb as normal. 2. stop bluetooth daemon It's not necessary to disconnect from networkmanager to trigger this. This time the first anomaly is a warning in get_work_pool. This time it says pppd, and it was trying to release the connection.

This is Gentoo built, Linux-3.9.2 (from kernel.org): This doesn't seem very helpful for me, all it's pointing to is some massive kernel table corruption.

[Bug 1165433] Re: Kernel 3.8.x panics on bluetooth DUN disconnect
For me, even with 3.9 this is the case. When I try to disconnect from DUN, at times I get thown to the text console with an oops. At times I just see the machine freeze in X11. At times the machine keeps working in X11 for a few seconds (or up to 1 minute), and in this case I can even see the oops in dmesg before the freeze or a crash. Does this happen on every architecture? Mine is X64, with intel graphics and Dell Computer Corp. Wireless 370 Bluetooth. If it happens on every possible architecture, it may be worth disabling BT DUN altogether, until someone upstream can look into it, since crashes and freezes may lead to data loss. Upstreams knows this since March, hence either it is very subtle to catch or there is really little interest in BT DUN. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1165433 Title: Kernel 3.8.x panics on bluetooth DUN disconnect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165433/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I saw this same issue in Gentoo Linux, and also suspecting kernel. I haven't gotten a chance to try newer kernels but 3.8.13-gentoo exhibits this issue 100% of the time.

I also have this problem on Xubuntu 13.04. When I disconnect the connection, there is a kernel panic. If you try to restart the machine without disconnecting, there is also a kernel panic.
