diBcom7000 / mt2060 (nova-t stick) scan crash

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

This stick seems to work pretty well, except that it tends to crash when 
scanning (not allways but ~ 1/2).

Is this a known issue?
Is there a known fix?


This is with :
- kernel 2.6.17
- latest v4l-dvb
- nova-s-ci on adapter0
- cinergyT2 on adapter1
- nova-t stick on adapter2

Attached is the interesting kernel log part.
(Note that of course, the stick isn't un/plugged during this operation).
