Wow...Almost!. I added vmalloc=256M, rebooted and, for the first
time, the card was fully initialized. I went into MythTV and was able
to see both tuners. Unfortunately, when I tried to use one of the
tuner there was no signal/picture. I decided to exit MythTV and
remove and re-add cx18. The card now failed in the exact manner as
before. Multiple attempts along with a reboot did not help. Back to
where we started.

I loaded and installed these drivers and left all timing settings
where you set them. No luck...Tried a reboot as well. Here is the

3. tveeprom and i2c_algo_bit debugging
I tried setting i2c_algo_bit debugging with 'modprobe is2_algo_bit
debug=1' and got an i2c_algo_bit: Unknown parameter `debug' error.
4. with tveeprom, i2c_algo_bit, and "cx18 debug=321" debugging.
Big output (320k)...I mailed this directly to you. Not sure if that
is the best approach.
Thanks for your help.
