[linux-dvb] Another Nova-T 500 Dual DVB-T Oops

Hi there,

I've just recently setup a Mythtv box with a Hauppauge Nova-T 500 
card.   The machine also has an Avermedia A777, but I believe only the 
Nova-T was active at the time.     The stack trace also has similarities 
with other reported oops's.  It did look a little different to the other 
recent oops, so I thought I'd report it.   Sorry if this is a duplicate 
report, I'm pretty new to all this.

I've had a couple of Oops since installing, and I've attached one of the 
outputs.  The other looked very similar.


I'm running the Ubuntu kernel image 2.6.20-4-generic.  I'm not sure how 
this relates to the upstream kernel release candidates .... and couldn't 
find the information on their web site.   Sorry.  I also noticed they 
have released a new version 2.6.20-5.

Let me know if there's anything I can do to help.

Regards,
Matt
