[DVB] dib0700 DVB devices not working with kernels >= 3.19.x (vivid + trusty) < 4.2.x (wily)

[stargazer]

Hello,

starting with kernel >= 3.19 (vivid) my USB TV-Stick DVB-T "Terratec Cinergy DT XS Diversity" stopped working.
=> BUG: unable to handle kernel NULL pointer dereference

This problem was not in kernel 3.16.x. (Utopic)

System: Kubuntu 14.04.2 64bit, kernel 3.19.x (lts-vivid, 3.19.0-18-generic #18~14.04.1-Ubuntu )

There is a bugreport available, where I have added my device-problem too and a patch is available.

https://bugzilla.kernel.org/show_bug.cgi?id=92301

Patch:
http://permalink.gmane.org/gmane.linux.kernel.stable/135755

Please add this patch to kernels >= 3.19 (LTS HWE Vivid kernel Trusty 14.04, Vivid 15.04 and newer; linux-generic-lts-vivid, linux-image-generic-lts-vivid, ... )

Thank you for your support!

Best regards, Bernhard

Hi.

The same here.
Trace attached.

But in my case, when the device is plugged, the system some times don't boot, too slow or gnome present serious problems like no mouse pointer. If the system is previously started without the device and then plug it, the system hangs.

Can't make the installation of the OS if the device is plugged.

Dear Ubuntu kernel team!

Do you know, when the patch will be included in kernel 3.19 in vivid and in lts-vivid for trusty?

Is there a patched kernel, which I can test for you ?

[stargazer (stargazer05)]

DVB patch from bugzilla.kernel.org attached:

https://bugzilla.kernel.org/show_bug.cgi?id=92301

Please include this patch in kernels >= 3.19 LTS HWE Vivid kernel Trusty 14.04, Vivid 15.04 and newer

I have also tested upstream kernels 4.0.6 and 4.1, but the problem is not solved, so the patch is not mainlined.

[Joseph Salisbury (jsalisbury)]

Thank you for providing a patch, and making Ubuntu better.

Can you provide some information on the status of the patch with regards to getting it merged upstream? Has it been sent upstream, what sort of feedback has it received, is it getting applied to a subsystem maintainer's tree, etc?

People affected by this bug are probably wondering why the kernel team doesn't just apply the patch and fix it. The reason is that the kernel team is reluctant (not opposed) to apply any patch to a stable kernel that is not from upstream. Applying patches that don't come from upstream add greatly to the support of the kernel as other upstream patches may touch the same area as the non-upstream patch and may prevent them from applying cleanly.

To submit your patch, send your patch with the detailed description/changelog and your Signoff (ending with Signed-off-by: your name <email>), to the emails listed from ./scripts/get_maintainer.pl drivers/SUBSYSTEM-DETAILS (the get_maintainer.pl is from the kernel sources). Once you have sent the patch upstream and it's accepted, please drop a note here so that we can cherry-pick/include the patch into Ubuntu kernel.

[stargazer (stargazer05)]

See bug report:
https://bugzilla.kernel.org/show_bug.cgi?id=92301

- Question from me:

Do you know when the patch will be included in the latest kernel and lts-kernels; 3.18, 4.0, 4.1?

- The writer of the patch, Thomas Reitmayr, answered the following:

I found the patch only in the linux-next tree, so that probably means 4.2, although it was forwarded to the linux-stable mailing list. Not sure how the process looks like for getting it into an lts kernel.

- Other posts from Thomas Reitmayr:

I submitted a patch to <email address hidden>. As described in the commit message the problem was introduced in kernel version 3.17 and concerns a few device types handled by dvb_usb_dib0700.
See http://permalink.gmane.org/gmane.linux.drivers.video-input-infrastructure/90691

Patch landed in linux-stable mailing list, see
http://permalink.gmane.org/gmane.linux.kernel.stable/135755

[stargazer (stargazer05)]

Furthermore I have tested kernels 4.0.6 and 4.1, but the problem is not solved.

[Joseph Salisbury (jsalisbury)]

Thanks for also sending this patch to upstream stable. The Ubuntu kernels will get this patch through the normal stable update process.

[stargazer (stargazer05)]

I have tested lts-wily kernel for precise => kernel 4.2 (4.2.0-7-generic #7~14.04.1).

With this kernel the usb dvb-t stick works again.
