I'm also getting problems with a PVR150 connected via svideo to an STB and
have up to now put it down to the hardware going bad. As you my system has
been very stable for over 5 years but in the last 2-3 months (since
updating to 0.24) I've been getting this random failure.

I've tried restarting the backend, unloading the ivtv driver and
modprobing it again to force a firmware reload to the card but to no avail

Possible that a new IOCTL is being used with the later backend s/w that
initiates this fault on the card? I've not changed kernel version (and
hence driver version) for over a year so I know its nothing at that level.

Sorry its a 'me too' but I thought you might like to know you are not alone!!
