Could it be applied to the tumbleweed kernel tree?
So i could test and report back, as the author doesn't have the hardware for testing.
Or
Could you revert the broken 3.0 patches back to the 2.6.39 version of this driver for further tumbleweed kernels until fixed upstream?

No, I won't apply patches which are not upstream yet, sorry. (Unless they are about security.) And DVB tree is sometimes slow to propagate :(.

I can build you a kernel for testing, if you want.

I don't think so. Hopefully it won't be that long before it gets upstream. You can branch kernel:stable project to the revision just before 3.0 update, if you want.

Yes, that would be great. I'm using the x86_64 desktop tumbleweed version.

I don't understand what you mean with "branch kernel:stable project". Can you give an example to me?

I downloaded and installed the test kernel but unfortunately the patch did not fix the problem. The BUG seams to be now after the initialization phase of the driver:

Hi Florian,
I'm using OpenSuse 11.4 with the tumbleweed kernel 3.0, unfortunately my DVB-USB Box stopped working with this kernel.
I goggled and found your patch at: https://patchwork.kernel.org/patch/1029612/
Jiri Slaby from OpenSuse build a testing kernel for me with your patch applied, but the patch did not
fix the problem,
please have a look at:

Thank you, Markus Stephan
Hi Markus!
Thanks for testing that patch. Here is a fixup to it. Can you give that a try? It's not the final answer (the naming of the functions sucks) but should work (tm).
(I forgot to fix up the usb_inout_op call sites in the vp702x-fe.c file and thus the buf_mutex was not initialized. With the attached patch applied, everything should work.)
Maybe Jiri can whip another kernel up for you to test?
Regards, Flo

Yes, it's there.
The test kernel did fix the BUG for me, the DVB-S USB-Box is working again.
Hope to see the patch + fixup in stable soon.
Thank you for building the test kernels!

Ok, I just submitted the patch to linux-media. You might want to retest it though, maybe I did some silly mistake...
Regarding the messages, can you turn on debugging in vp702x (modprobing it with module param debug 3 ) after applying this patch?
It will show where the device is not responding. I guess it's a problem in the protocol implementation, which is hard to fix without hw-specs. But let's see what that debugging turns up.
Regards, Flo
Final patch from Florian + debug patch for diagnosing annoying: vp702x: usb in operation failed. (-110) error messages.
Maybe you could find some time for building an other test kernel for me ...
Thank you, Markus Stephan

Hi Florian,
Jiri made an other test kernel for me with your final + debug patch applied.
The box works fine and the message: vp702x: usb in operation failed. (-110)
seams to be triggered by: vp702x_fe_set_frontend+0x156/0x1a0 [dvb_usb_vp702x]
Full dmesg is attached.
Thank you, Markus Stephan
Hi! Here is a patch to check if that failing op is even necessary.
But even if it works I don't feel comfortable of suggesting this to be applied, since I don't have any overview about the hardware supported by this driver. Maybe Patrick has any opinion on this, he wrote this driver after all :)
Regards, Flo
Final patch works fine,
debug patch turns out that the function: vp702x_fe_set_frontend() is the source of the:
vp702x: usb in operation failed. (-110) error message storm.
Florian made a patch to test if this failing usb in op is necessary on my box.

Maybe he could fix the driver to not pollute the system log with hundreds of: 'vp702x: usb in operation failed. (-110)' messages

Yes, due to build error. As this is the second time, ask him to provide you with patches that don't cause build errors. It's (hopefully) fixed and building now at the usual place.

Hi Florian,
could you please check your above patch, Jiri got build errors while trying to build an other test kernel for me.
http://download.opensuse.org/repositories/home:/jirislaby:/vp702x/standard/
https://bugzilla.novell.com/show_bug.cgi?id=709440
Thank you, Markus
Oh, I'm sorry. vp702x_usb_out_op had to be exported too, for this to work. I actually had it in my tree (hence it compiled for me), but forgot to add it to the patch I send you.
From the bugzilla comment and Jiri's last sentence , I take it Jiri
already corrected it and got it building?
(I attached the complete patch for reference.)
Regards, Flo
p.s.: Sorry jiri, will double check twice any patch I sent Markus from now on :-) Thanks for building these kernels for him.

I probably was too impatient then ...
However, the new test kernel works pretty good and reduces the 'vp702x: usb in operation failed. (-110)' messages a lot.
But there are still some cases left in the driver, which seams to trigger the above error message.
Hopefully Florian is able to submit one last patch to address this issue and we could finally close this bug as 'fixed'.

Any updates on this? have you heard back from him?
No, no reply until now.
New kernel 3.1 still oopses after loading the vp702x driver, even so a working and tested patch exists since months now.
Since the real bug is fixed and only some cosmetic problems left, I think you could close this bug as resolved.
