Hello,

when loading the dvb-modules, dmesg shows errors from ves1820:

# modprobe dvb-ttpci
# dmesg
[cut]
Linux video capture interface: v1.00
saa7146: register extension 'dvb'.
ACPI: PCI Interrupt Link [LNKB] enabled at IRQ 10

dvb-ttpci: A frontend driver was not found for device 1131/7146 subsystem 13c2/0002
dvb-ttpci: found av7110-0.

Though I have two cards (1 premium and one budget) currently 

# ls -la /dev/dvb/adapter0/

only shows

(Shouldn't be the device number 250 ?)

There's no adapter1

I tried several times with several kernel versions (2.4 also). Sometimes I was lucky, so there was an adapter1, but
there never was a frontend found and persistantly I find these lines in dmesg:

ves1820: ves1820_readreg(): readreg error (reg == 0x1a,ret == -121)
dvb-ttpci: A frontend driver was not found for device 1131/7146 subsystem 13c2/0002

Is there a bug in the frontend-module ?


Im thankfull for any help as I have been trying for almost 4 weeks now....

Best regards,
Armin

This is my hardware:

0000:00:0d.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
        Subsystem: Technotrend Systemtechnik GmbH Technotrend/Hauppauge DVB card rev2.1
        Flags: bus master, medium devsel, latency 64, IRQ 10
        Memory at ff000800 (32-bit, non-prefetchable)

0000:00:0e.0 Multimedia controller: Philips Semiconductors SAA7146 (rev 01)
        Subsystem: Technotrend Systemtechnik GmbH Technotrend-Budget / Hauppauge WinTV-NOVA-C DVB card
        Flags: bus master, medium devsel, latency 64, IRQ 11
        Memory at ff000400 (32-bit, non-prefetchable)

This my kernel on a gentoo-box (DELL Optiplex GX-1 A10):
development-sources-2.6.10-r1 ; DVB is patched via CVS

I closely followed the gentoo-instructions from the vdr-wiki (http://www.vdr-wiki.de/wiki/index.php/Gentoo_VDR), I only head to take a more recent kernel-version.
