cx18: Two cards, both detected, only cx18-0 is working, input/output error when accessing cx18-1
|
|
Hello everyone,
I'm new to the cx18 driver, but familiar with the ivtv family.
I am building a new system that has two HVR-1600s in it. The motherboard is
a Via C7 based board with a dual PCI riser. It has 1GB of memory.
I am running a custom built 2.6.27 (final) kernel with the cx18 and ivtv
drivers built in.
After adding vmalloc=192M to my kernel boot line, both cards appear to
initialize properly:
Here is my dmesg output segment:
cx18: Start initialization, version 1.0.0
cx18-0: Initializing card #0
cx18-0: Autodetected Hauppauge card

After boot, I can talk to and utilize /dev/video0 relatively normally (I am
getting a slight jerkiness in watching video off /dev/video0 but I can
investigate that one later).
cat /dev/video0 > sample.mpg
Yields the firmware load info in /var/log/messages as well as a file with a
size greater than zero
