[linux-dvb] card firmware/interrupt issues

[Hamish Moffatt <hamish@cloud.net.au>]

Hi,

I've had problems in the past with FDSR and FBUS errors from the BT878
on my Aver761 card. These were particularly common during high I/O times
eg MythTV starting to record off two DVB cards at once.

Tonight I had a weird problem where both my DVB cards reported errors at
once. The Nova-T gave an interrupt warning, and the Aver761 output FDSR
errors for the next *12 minutes*. The system was idle at the time, as
best I can workout. Certainly Myth wasn't recording.

Both cards were tuned to the same station, though the demux wasn't
enabled. Is it possible for received station data to cause microcode
errors on these two cards?

The only other factor is that I added a Wifi card to the system and it's
in the slot next to the Aver761. However it's not enabled yet (no
drivers etc). Has anyone had issues with interference between Wifi and
DVB cards?
