That line was already commented out (#dtoverlay=vc4-fkms-v3d) in config.txt so I blacklisted module v3d, works now better with 1013 kernel. Thanks.

[Kernel-packages] [Bug 1189998] Re: bluetooth disconnection corrupts memory and causes kernel panic
I managed to find one more bug report similar to this one. So now there
are at least four bug reports (including this one) here in Launchpad on
this problem:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1144322
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165433
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1189998
https://bugs.launchpad.net/ubuntu/+source/linux-lts-raring/+bug/1256811
Anyway, if these are about the same bug that I think they are, the bug
has now been completely fixed in kernel version 3.14, though kernel
version 3.12 included some of the fix. Also there was one previous fix
that is also needed that I think was backported to stable before 3.12.
I think I manged to list all the necessary commits, Here are links to
the commits, in case they need to be backported:
The first fix (pre 3.12?):

bluetooth disconnection corrupts memory and causes kernel panic
Status in “linux” package in Ubuntu:
Fix Released
Status in “linux” source package in Raring:
Confirmed
Status in “linux” source package in Saucy:
Fix Released
Bug description:
This bug is present on kernels v3.8-rc1 and beyond and was exposed by commit
ecbbfd44.
To reproduce:
1) Pair a bluetooth device that is capable of being easily powered down (a
phone for example)
2) Configure /etc/bluetooth/rfcomm.conf to connect to device. For example:
rfcomm0 {
bind no;
device XX:XX:XX:XX:XX:XX;
channel XX;
comment phone;
}
3) Type 'rfcomm connect 0'.
4) On the device power down the bluetooth component or power down the device.
5) Eventually the machine will crash, I've found that exec'ing another
program will cause the crash easily.

[Kernel-packages] [Bug 1144322] Re: [Toshiba Satellite A80] Kernel 3.8.x Panic when disconnecting from network manager via ppp0
I managed to find one more bug report similar to this one. So now there are at least four bug reports (including this one) here in Launchpad on this problem: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1144322 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165433 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1189998 https://bugs.launchpad.net/ubuntu/+source/linux-lts-raring/+bug/1256811 Anyway, if these are about the same bug that I think they are, the bug has now been completely fixed in kernel version 3.14, though kernel version 3.12 included some of the fix. Also there was one previous fix that is also needed that I think was backported to stable before 3.12. I think I manged to list all the necessary commits, Here are links to the commits, in case they need to be backported: The first fix (pre 3.12?): https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1d9e689c934bd5ecb0f273c6c65e0655c5cfee5f The fixes in 3.12: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=396dc223dd36edd218650d042a07c5e61f022c5b https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ebe937f74b8a72cf3ceeae5c2194a160bb092901 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=54b926a1434e817ca84cb090f36b56763e192470 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=cad348a17e170451ea8688b532a6ca3e98c63b60 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ece3150dea382c7c961fe2604332ed3474960d25 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ffe6b68cc5999a3f91a15b6667e69e14186e337d https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=29cd718beba999bda4bdbbf59b5a4d25c07e1547 And finally the fixes in 3.14: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5b899241874dcc1a2b932a668731c80a3a869575 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e228b63390536f5b737056059a9a04ea016b1abf https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4a2fb3ecc7467c775b154813861f25a0ddc11aa0 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f86772af6a0f643d3e13eb3f4f9213ae0c333ee4 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1144322 Title: [Toshiba Satellite A80] Kernel 3.8.x Panic when disconnecting from network manager via ppp0 Status in “linux” package in Ubuntu: Incomplete Status in Arch Linux: Fix Released Status in Gentoo Linux: Fix Released Bug description: Using: Ubuntu 12.04 (precise) 32-bit Machine: Laptop / old Toshiba / Celeron processor Installing Kernel from: http://kernel.ubuntu.com/~kernel-ppa/mainline/; Apport disabled and uninstalled, so can't provide debug/log details (this to make the machine run a bit faster, have been doing so since 10.04).

This bug is seen on quantal using the kernel from PPA mainline. Tested with 3.8.0 to 3.8.6. Since 3.8.x is going to be the raring kernel I believe that this should definitely be fixed before raring is shipped. Seen on: DELL E6500 with kubuntu quantal 12.10 64 bit and as said, kernel 3.8.6 from the mainline ppa. The machine has a Dell Computer Corp. Wireless 370 Bluetooth Mini-card (connected via an internal usb connection). The issue is shown when connecting to the internet via a Samsung Galaxy S plus phone, using a bluetooth DUN connection. It is reproducible every time. How to reproduce: 1) Use the bluetooth applet to discover the phone and associate to it. 2) Use network manager to setup a DUN connection with the phone through your APN 3) Connect to the internet via bluetooth DUN (connection works perfectly) 4) Disconnect from the network manager. At the same time you disconnect, the GUI session is terminated and the kernel panics, briefly showing a panic log on the screen. Note that: a) The issue is not present using the standard ubuntu quantal kernel b) The issue is not present using kernels from the mainline ppa before 3.8 (e.g., 3.7.x is fine for all x) c) The issue is not present when connecting to the internet using a USB mobile dongle (e.g. Huawei usb key) This looks pretty serious to me: kernel does not sync when panicing and there is a serious risk of data loss; connecting to the internet via a smart phone using bluetooth DUN seems to be something that one should take for granted on any modern OS. Furthermore, points a) and b) above show that this is a *regression* over previous kernels.

Bug description:
This bug is present on kernels v3.8-rc1 and beyond and was exposed by commit
ecbbfd44.
To reproduce:
1) Pair a bluetooth device that is capable of being easily powered down (a
phone for example)
2) Configure /etc/bluetooth/rfcomm.conf to connect to device. For example:
rfcomm0 {
bind no;
device XX:XX:XX:XX:XX:XX;
channel XX;
comment phone;
}
3) Type 'rfcomm connect 0'.
4) On the device power down the bluetooth component or power down the device.
5) Eventually the machine will crash, I've found that exec'ing another
program will cause the crash easily.

This bug is seen on quantal using the kernel from PPA mainline. Tested with 3.8.0 to 3.8.6.

At the same time you disconnect, the GUI session is terminated and the kernel panics, briefly showing a panic log on the screen. Note that: a) The issue is not present using the standard ubuntu quantal kernel b) The issue is not present using kernels from the mainline ppa before 3.8 (e.g., 3.7.x is fine for all x) c) The issue is not present when connecting to the internet using a USB mobile dongle (e.g. Huawei usb key) This looks pretty serious to me: kernel does not sync when panicing and there is a serious risk of data loss; connecting to the internet via a smart phone using bluetooth DUN seems to be something that one should take for granted on any modern OS.

[Kernel-packages] [Bug 1189998] Re: bluetooth disconnection corrupts memory and causes kernel panic
Gianluca Anzolin writes on bluetooth-linux mailing list that though his
tty refcount patch series is needed, more work is required to fix the
problem. If I understood his mailing list message correctly, the system
locks up when the device is released even after his patches have been
applied.

Bug description:
This bug is present on kernels v3.8-rc1 and beyond and was exposed by commit
ecbbfd44.
To reproduce:
1) Pair a bluetooth device that is capable of being easily powered down (a
phone for example)
2) Configure /etc/bluetooth/rfcomm.conf to connect to device. For example:
rfcomm0 {
bind no;
device XX:XX:XX:XX:XX:XX;
channel XX;
comment phone;
}
3) Type 'rfcomm connect 0'.
4) On the device power down the bluetooth component or power down the device.
5) Eventually the machine will crash, I've found that exec'ing another
program will cause the crash easily.

[Kernel-packages] [Bug 1165433] Re: Kernel 3.8.x panics on bluetooth DUN disconnect
Gianluca Anzolin writes on bluetooth-linux mailing list that though his tty refcount patch series is needed, more work is required to fix the problem. If I understood his mailing list message correctly, the system locks up when the device is released even after his patches have been applied. Source: http://marc.info/?l=linux-bluetoothm=137788497602145w=2 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1165433 Title: Kernel 3.8.x panics on bluetooth DUN disconnect Status in “linux” package in Ubuntu: Incomplete Bug description: Issue is obviously in the kernel that should not panic in any circumnstances. This bug is seen on quantal using the kernel from PPA mainline. Tested with 3.8.0 to 3.8.6. Since 3.8.x is going to be the raring kernel I believe that this should definitely be fixed before raring is shipped. Seen on: DELL E6500 with kubuntu quantal 12.10 64 bit and as said, kernel 3.8.6 from the mainline ppa. The machine has a Dell Computer Corp. Wireless 370 Bluetooth Mini-card (connected via an internal usb connection). The issue is shown when connecting to the internet via a Samsung Galaxy S plus phone, using a bluetooth DUN connection. It is reproducible every time. How to reproduce: 1) Use the bluetooth applet to discover the phone and associate to it. 2) Use network manager to setup a DUN connection with the phone through your APN 3) Connect to the internet via bluetooth DUN (connection works perfectly) 4) Disconnect from the network manager. At the same time you disconnect, the GUI session is terminated and the kernel panics, briefly showing a panic log on the screen. Note that: a) The issue is not present using the standard ubuntu quantal kernel b) The issue is not present using kernels from the mainline ppa before 3.8 (e.g., 3.7.x is fine for all x) c) The issue is not present when connecting to the internet using a USB mobile dongle (e.g. Huawei usb key) This looks pretty serious to me: kernel does not sync when panicing and there is a serious risk of data loss; connecting to the internet via a smart phone using bluetooth DUN seems to be something that one should take for granted on any modern OS. Furthermore, points a) and b) above show that this is a *regression* over previous kernels.

The fix being discussed on Bluetooth mailing list has already been

way to mainline kernel (probably 3.12).

However, the patch series is apparently too extensive to consider for
-stable [1]. So another solution is required for stable kernels. Though
no one seems to know what the right solution for stable kernels is [2].

Note that: a) The issue is not present using the standard ubuntu quantal kernel b) The issue is not present using kernels from the mainline ppa before 3.8 (e.g., 3.7.x is fine for all x) c) The issue is not present when connecting to the internet using a USB mobile dongle (e.g. Huawei usb key) This looks pretty serious to me: kernel does not sync when panicing and there is a serious risk of data loss; connecting to the internet via a smart phone using bluetooth DUN seems to be something that one should take for granted on any modern OS. Furthermore, points a) and b) above show that this is a *regression* over previous kernels.
