Hello all,
I have a Cinergy T2 Usb Box connected to my Linkstation NAS running
Debian Testing armel
and a 2.6.25.1 vanilla Kernel.
the Cinergy module loads just fine but when I try to tune a channel I
get a kernel Oops ( see below ).
What I've tried so far:
asking the google crystal ball... no realy good answer...
different kernel:
vanilla 2.6.25.1
orion git repositry
used this kernels with hg repositries of
v4l-dvb and v4l-dvb-experimental
This is the output of a w_scan run:
mythvdr:/usr/src/w_scan-20080105# ./w_scan
w_scan version 20080105
Info: using DVB adapter auto detection.

At this point the serial console becomes a one way connection, I get
output but it doesn't take input anymore.
ssh logins to the box are still possible and also init 6 works and the
box does a clean reboot.
Additional information: the Cinergy works fine when attached to my AMD64
Desktop running debian etch and the debian
kernel 2.6.18-6-amd64
it also works on my NSLU2 NAS running debian etch for ARM and kernel
2.6.18-6-ixp4xx
I tried to compile this debian kernel for the Linkstation but it did not
boot... will try to find out what's wrong
but would rather use the vanilla kernel.
I hope I gathered all needed informations to help me fix this problem.
Greetings
Ingo

Hello everyone...
a few days ago I bought e Pinnacle PCTV200e to try if it works with my
Linkstation. After getting some drivers for it from here:
http://ubuntuforums.org/showthread.php?t=511676&page=8
As result I just got the same kernel oops, only triggered by the dvb_usb
module instead of the cinergyT2 one.
Today I found a patch sent to this list on 01/20/2008 by Michele
Scorcia. Although it is for kernel 2.6.20.4 and written to fix a problem
on a mips platform the description of the problem came close to mine. So
I applied it to the usb-urb.c from the above archive and built the modules.
After that the oops was gone and the PCTV runs without problems.
The cinergy driver still triggers the oops but i think that's normal
cause it does not use the dvb-usb module and would need a separate patch.
The new cinergyT2 driver from Tomi Orava works just fine so I give it a
chance instead of fixing the old one.
Another reason for this is that I tried both receivers on my desktop
with the same kernel and v4l-dvb sources as I use on the Linkstation and
couldn't make them run both at the same time. dmesg shows no errors but
w_scan hangs when both drivers are loaded. Either receiver alone works
great but together none does.
This problem does not exist with the new driver.
Here's the patch I use, only difference to the one from Michele Scorcia
are the line numbers:
--- v4l-dvb/linux/drivers/media/dvb/dvb-usb/usb-urb.c 2008-05-05

}
return 0;
Would be great if this oops cause for arm and mips and maybe others
could be fixed in the v4l-dvb source.
Many thanks to Michele Scorcia for finding and fixing the problem :)

Is it the same ManufacturerID/VendorID as the cinergyT2 device or did you make some adaptations to make your Pinnacle device to work with the cinergyT2 driver?

I hope Tomi will be able to finalize his patch so we will be able to replace the old one.
The old driver is monolithic and does not follow the dvb framework evolutions/bug corrections.

Well, think I was a bit unclear here.
I don't use the cinergyT2 module with the Pinnacle device.
The v4l-dvb drivers I found on the ubuntu forum contains a separate
driver for the PCTV200e. What I was trying to say is that both drivers
trigger the same oops, in case of the PCTV it originates in dvb-usb.ko
and in case of the cinergy in cinergyT2.ko

Hope so too, as I stated in my reply to the 'Tester wanted ...' thread
it works good except the signal recognition is very poor compared to the
old driver.

Hi,
just a "mee too". I use Tomi's driver for months and it works like a
charm.
