Hi all, I'm new to the list so feel free to direct me somewhere else if
the following is OT.
I get a hard lock on my machine, no response to Alt-Sysrq T, dead to the
world, when running the mentioned card with a Conax cam to record
encrypted DVB-T channels. I have had the thing running through a night
and recording a couple of shows, but mostly it locks up within seconds
from the start of recording, with no pattern that I can see
I am running gentoo, and I have tried both the latest stable kernel with
its modules, the latest unstable kernel with its modules and the modules
from git as per
<http://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers>,
the "Basic" approach. My current kernel is:
# uname -a
Linux medisin 3.5.4-gentoo #1 PREEMPT Wed Sep 26 14:23:09 CEST 2012 i686
Intel(R) Pentium(R) 4 CPU 2.00GHz GenuineIntel GNU/Linux
Should I maybe loose the "preempt" ?
The last messages I get in my logs is
mythbackend: TVRecEvent tv_rec.cpp:3989 (TuningNewRecorder) - TVRec(7):
rec->GetPathname(): '/apub/media/mythtv/2201_20120926203000.mpg'
kernel: [ 98.144753] ttusb2: tt3650_ci_read_cam_control 0x01 -> 0 0x00
debug: medisin kernel: [ 98.144753] ttusb2: tt3650_ci_read_cam_control
0x01 -> 0 0x00
Everything up to that point seems hunky dory, such as 30 seconds earlier :

.... and these go on ...
I have miles of logs, just tell me what to post :-)
Other interesting points about the system, in no particular order the
box is a fairly old system, which has had some issues. I have repaced
some popped caps, I believe I found them all. I have removed the usb
flat-bed scanner so the draw on power should be /less/ than before,
considering the Technotrend has its own power. I have made sure that
lsusb says usb 2.0 on the bus. What else should I check ?
Whith hope, Håkon :-)
