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, except 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.

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
<snip>
The options line 1 is used widely and only worth changing if all else fails.
Ok, thanks.
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...
