Nebula PCI card and weird IRQ message

[ivan_alias]

I'm using a Nebula PCI DTT card and it seems to be working just fine in MythTV, however I am getting this filling up my messages log:

There are lots and lots of it, my messages log runs into the thousands of lines! Then syslogd gets into trouble and the machine grinds to a halt..

Im using Fedora core 3 with 2.6.10-1.770_FC3 kernel and the DVB modules following the guide here:

It doesnt seem to affect operation at all, but I'd like to know what it all is and what I can do to stop it!?

Thanks for any help
