Now, this is one we have an issue with: it's got a bttv card, and motion running on it. It's a Dell PE R720. For some reason, it has never liked the card: 20 min after reboot, it says fatal bus error... but nothing's wrong, and it runs just fine. Well, expect that we need to keep it on the 2.6.32-431.20.3 kernel, because *everything* later, it randomly starts rebooting, several times a day.
But we've never had anything like this, and I've never seen anything like this: the bttv module was throwing a ton of IRQ lockup errors. Restarting motion didn't help. So I was wondering if the issue was with the bttv kernel module, so I rmmoded that, then modprobe bttv... and that was all she wrote. The system lost network connectivity.
Ok, I go over to the rack, and plug in the monitor-on-a-stick, and that's where it got very strange, and I've never seen anything like this: I turn up the monitor... and see it announcing it had seen a new USB device (the keyboard)... and no login, it kept printing copying data [<percentage done>%] When it hit 100%, it rebooted.
So - has anyone ever seen this behavior? Anyone have an idea what it was copying?

Hi,
What is the make/model of the card?
Are you supplying options when loading the bttv module?

On and off, I've been googling to find if there's something I can tell it, or the kernel on boot. Currently, I have, in /etc/modprobe.d/bttv: options i2c-algo-bit bit_test=1 options bttv gbuffers=16 card=98,98,98,98,98,98,98,98 radio=0,0,0,0,0,0,0,0 tuner=4,4,4,4,4,4,4,4 chroma_agc=1 combfilter=2 full_luma_range=1 coring=1
which is something I got from googling as to how to get it working. Think there's something in that - the first line? that is not a good thing?

Hi,
The options line 1 is used widely and only worth changing if all else fails.
The second options line option of combfilter by docs indicate there is no 2 option and is enabled by default, so you can remove that option to test.
I would enable two possible compatibility options and see if that helps.
triton1=0/1 - for Triton1 (+others) compatibility.
vsfx=0/1 - yet another chipset bug compatibility bit
The triton1 insmod option sets the EN_TBFX bit in the control register. The vsfx insmod option does the same for EN_VSFX bit. If you have stability problems you can try if one of these options makes your box work solid.

Thanks very much. I'll try those as I have the chance; unfortunately, it's not something I can do frequently, as the server's in use, and exporting project directories to users... oh, and it is actually running motion for surveillance of the room...

Ok, I've been doing some research, partly refreshing my memory, since we bought these 2-3 years ago. As you note, above, it *says* it's an iTuner Spectra8; *however*, when I look at bttv-cards.c, what I see is that *it* thinks that such a card has *one* video and one audio. In fact, this is a Bt878, and it has *four* inputs for each, with four chips on the card, one for each channel. The nearest thing to it *appears* to be a Provideo PV150, card=98 (which is why I have that card= line in the bttv.conf).
Now that I'm thinking about it, and while googling, I looked for the provideo 150, and what *should* have been the link took me to one for a provideo 950, with *16* inputs. Does anyone have opinions on: 1. should I change the card-, radio=, and tuner= to only have four, instead of 8, values? I realize that it multiplexes for 8, but.... 2. What is "coring"?

Hi Mark,
It did specify spectra 8 in your lspci output. Below is product page.
http://www.ituner.com/spectra.htm
In my research I did find this related page.
http://www.linuxconsulting.ro/spectra8/
This does state that with latest internal driver, it is detected and works as the ProVision 150. The card=98,... is correct.
The matter of reducing all the settings to 4 rather than 8 may help.
coring is a luma setting. See:
https://www.linuxtv.org/wiki/index.php/Bttv#insmod_Options
Not sure and someone else maybe can shed better light on the setting. By default it is disabled and I would tend to think it can be removed.
Regards
Phil

Hi Mark,
You have the setting of 16 which maybe correct for how many feeds you are taking/processing. If less I maybe tempted to drop it to the default 8. If the device is running as close to or at default and no hickups - all the better. :-)
