Hi,
I've a Advace Logic's PCI Captivator capture card, it is a BT848A,
without tuner and without audio, just one RCA and one SVHS video input.
This board works fine with kernel 2.2.18, when loading bttv modules this
way:
# modprobe bttv triton1=1 vidmem=0xe28
it detects the board as an Hauppauge Old, this is the kernel log in
/var/log/messages:
Jan 22 15:55:45 bridge kernel: i2c: initialized
Jan 22 15:55:45 bridge kernel: Linux video capture interface: v1.00

Jan 22 15:55:45 bridge kernel: bttv0: model: BT848(Hauppauge old)
The problem starts when I upgraded to kernel 2.4, I noted a lot of
diferences in it and I'm unable to make the board work.
I've put the following information on /etc/modules.conf:
# i2c
alias char-major-89 i2c-dev
options i2c-core i2c_debug=1
options i2c-algo-bit bit_test=1
# bttv
alias char-major-81 videodev
alias char-major-81-0 bttv
options bttv card=0 triton1=1
options tuner debug=1
I tried with card=2 and without any parameter too, but in this way, the
modules loads, showing the following in /var/log/messages:
Jan 27 21:12:40 bridge kernel: i2c-core.o: i2c core module

Jan 27 21:12:43 bridge kernel: i2c-core.o: driver i2c TV tuner driver
registered.
But when I start a video4linux application (tried xawtv), the system
completely locks up, needing a hardware reboot.
Just to give some more information, the board is detected in /proc/pci
as:
Bus 0, device 11, function 0:
Multimedia video controller: Brooktree Corporation Bt848 TV with DMA
push (rev 18).
IRQ 11.
Master Capable. No bursts. Min Gnt=16.Max Lat=40.
Prefetchable 32 bit memory at 0xe2800000 [0xe2800fff].
Can somebody help me?
Best Regards,
