Hi,
I'm using a Twinhan Vision Plus DVB-T clone (VP3020) in Australia which
is being auto detected and working on one machine, but fails to be
auto-detected and work on another AMD64 machine. On both machines I'm
using the 2.6.16 kernel and I've just downloaded and applied the
hg/v4l-dvb tree on top.
The problem seams to resemble another post where the card failed to work
when inserted with another card. [Post: Twinhan Vision Plus & WinFast
DTV1000-T, Feb06 from Matt Pratt].
The symptom seams to be that the PCI Subsystem ID and Subsystem Vendor
are cleared to zero in the PCI config space of the card. See lspci -xvv
output below.
This causes a "dst_get_device_id: Write not Acknowledged!" in dst.c when
probing for the card. Here is the dmesg output
modprobe bttv debug=8
modprobe dst verbose=8
dvb_bt8xx debug=8

I have also tried the acpi=off kernel boot param, I've updated the MB
bios, swapped the card around to different PCI slots with no avail.
Any suggestions?
