Hi,
Get an occasional Oops which can occur either when the device is in use,
or idle.. and it only usually happens after several hours of uptime with
the module and device loaded. The 'oops' seems to directly correlate
with the device appearing to disconnect and reconnect via USB (but
nothing physical has changed).
In this example, the box was booted at 21:50 and the Oops occurred at
03:13 when the device was idle:

Hi,
this will be fixed in upcoming kernel releases, there's already a patch
for that in the video4linux/dvb repository on linuxtv.org.
So if you update your v4l-dvb drivers that problem shouldn't occure anymore.
