This is not an error. If a DVB driver is unloaded, its IRQ is unused and 
ACPI disables this IRQ line. As soon as the driver gets loaded again, 
the ACPI IRQ will be enabled again.

For me, this is shown in syslog like this:

kernel: ACPI: PCI interrupt for device 0000:00:13.0 disabled
kernel: saa7146: unregister extension 'budget dvb'.
[...]
kernel: ACPI: PCI Interrupt 0000:00:13.0[A] -> Link [LNKA] -> GSI 11 
(level, low) -> IRQ 11
kernel: saa7146: register extension 'budget dvb'.

Cheers,

Udo
