Subject: DVB (Nova-T) trouble after system crash

Hi,

I have a Nova-T card in my PVR system since most of a year.  Its been
working just fine for all that time.

My system runs DVB driver from quite a while back - out of the CVS as of
26th April 2002

I use dvbstream to capture off the Nova-T card.

All was fine until my system crashed whilst capturing something yesterday.

I don't know whaat caused that crash.  The system had been up without
problems since 11th October - more than 3 months - in which time it will
have recorded 100+ DVB programs.

Since that time, an attempt to use dvbstream to capture something crashes
my box immediately.  The drivers themselves load fine, tzap and dvbtune
don't cause any problems.  I also booted my machine into Windows 2000 and
the card appears to work fine with the Windows software supplied with the
card.

I wondered whether my CPU is damaged - my box does run hot - but other
stuff seems to be OK.  I wondered whether the DVB card was damaged - but
that works OK in Windows.

My DVB card is currently sharing interrupts with my second on-board IDE
controller - irq 10 - but I believe it has always been that way.  The box
is full of cards so its impossible to avoid IRQ sharing.

The crash is reproducable - I've tacked a ksymoops output at the end.

I will update the DVB drivers, and dvbtools.

But - it seems so strange to suddenly start having this problem, so any
ideas will be very welcome!

Thanks,
Steve
