Hello, I also had this issue.
I am using Linux raid (mdadm) and with a 6 drive array it would always spit out that error when writing from the hauppage to the raid array (ie, recording video). After endlessly trying to balance my irq's, trying all combinations of manual assignments, no acpi, no apic, no-usb, vise-versa, etc. Nothing seemed to work. I even tried different OS's (knopp myth, ubuntu dapper, slackware). In the end I am not sure if it was being caused by my highpoint sata card (on board) or the ivtv unit. If I use them together they just don't work, but the array functioned perfectly all other things set aside. So now I only have a 4 disk array that uses only ide channels on my Intel controller, the array is a bit smaller but it works fine.
