Thanks, Andy. I was having some mailer problems, and missed it.
This is a hard machine freeze. Only hardware reset will get a
response.
I did the modprobe debug=0x7ff, then did a tail -f /var/log/kern.log &
and then cat /dev/video0 >/dev/null
I see (transcribing because the machine is frozen):
Preparing for firmware halt
Stopping VDM
Stopping AO
pinging (?) APU
Stopping VPU
Resetting Hw Blocks
Stopping SPU
init Encoder SDRAM pre-charge
init Encoder SDRAM refresh to 1us
init Decoder SDRAM pre-charge
init Decoder SDRAM refresh to 1us
Sleeping for 600 ms
....freeze...
I hit reset, and when it came back, when I did a modprobe I kept
getting that it couldn't get an IRQ (after varying amounts of time...
sometimes immediately after the modprobe, sometimes after messages
sent from tuner-simple, and everywhere in between), so I halted it and
power-cycled it, and then it installed properly, so I did cat /proc/
kmsg & cat /dev/video0 >/dev/null and saw:

Repeat, this time I realized that rsyslog might be eating some of the
messages, so I stopped it... I got the firmware: and the Loaded
messages for both firmware (enc and dec), then
...freeze...
Repeat this time in single-user, starting udev getting

...not frozen... I could ^C out of the cat, so I tried the cat again,
and got a couple of DMA timeouts, so I ^c again, and then tried a cat /
dev/video0 >video-capture, but the resulting file is 0 bytes long.
So I tried the modprobe -r ivtv;sleep 1;modprobe ivtv debug=0xffff and
then when I tried the cat I got

Loaded v4l-cx2341x-enc.fw firmware (376836 bytes)

Encoder firmware dead!
Failed to initialize on minor 0
which seems to be repeatable with additional cat /dev/video0.
So I tried the reboot in single-user mode again and it couldn't get an
IRQ, but it worked on the next attempt. I got the first 4 lines from
last time, then ...freeze...
After a few more reboots for luck... one that couldn't get an IRQ and
the rest with the same 4 lines before freezing, I'm giving up for the
night.
Is my card fried in some way?
Is there some interaction with the Atom D410 that triggers a bug in
the driver? I had hyperthreads on for these experiments, but
previously when I turned it off, it didn't make any difference.
Is there something wrong with my firmware? The MD5 sums end in:
8883f3ecb68 dec.fw
2ef0c50ef48 enc.fw
4557353eacc init.mpg
Thanks for any guidance you may have!
