Hi,
I'm playing around with an AMD64 system, an Air2PC card on linux
2.6.11.7 and the latest CVS version of dvb-kernel and I'm getting
these errors when I load flexcop-pci:
b2c2-flexcop: B2C2 FlexcopII/II(b)/III digital TV receiver chip loaded
successfully
flexcop-pci: will use the HW PID filter.
flexcop-pci: card revision 2
ACPI: PCI Interrupt Link [APC1] enabled at IRQ 16
ACPI: PCI interrupt 0000:01:08.0[A] -> GSI 16 (level, low) -> IRQ 209
DVB: registering new adapter (FlexCop Digital TV device).
