And they work very nicely. Thanks.

I'm afraid savecore wasn't able to save a valid core if yo really
want a trace I will recompile the original modules and generate.
The message I had jotted down on a sticky note are:

cxm0: unknown tuner code 0x2c
cxm0: could not initialise tuner
iicbus0: detached
iicbb0: detached
panic: free: multiple frees

Wish there were details to report. The last couple weeks there have been
a couple threads in the ivtv mailing list about the data stream
freezing. It has been attributed to DMA problems and so far the
main change has been to add some debug output to the driver.

I will try yanking out the other cards and see what happens.

Great, I look forward to seeing a 5.2 version.

I was testing your new patches and had the following results

First capture hung after about 5-10 minutes.

I ^Ced the capture, unloaded the modules and reloaded them and
got a panic

rebooted

Next capture 30 minutes no problem
Next capture 30 minutes no problem
Next capture 90 minutes no problem

at that point I tried

mplayer -cache 8192 /dev/bktr0

it was working. I exited mplayer, changed channels tried again.
Repeated that a few times (OK, I'm easily amused :-) I decided
to leave mplayer running and go to bed. When I checked on it
in the morning, I saw the following message from mplayer:

-----
Too many audio packets in the buffer: (4096 in 8257536 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.

[repeated 4 or 5 times]

Exiting... (End of file)
-----

I checked /var/log/messages for kernel output and found

Jan 22 22:00:29 /kernel: cxm0: encoder dma not enough buffer space free
Jan 22 22:01:03 last message repeated 106 times
Jan 22 22:01:03 last message repeated 2 times
Jan 23 01:47:10 /kernel: cxm0: encoder dma not enough buffer space free
Jan 23 01:47:30 last message repeated 170 times
Jan 23 01:48:37 last message repeated 20 times

the 'not enough buffer space' messages would have started about a half
hour after I went to bed.
