Motion - Support Question 2005x 02x 21x 213030

FC3 with Motion crashing

Question

Running motion-3.1.18 on FC3 HP TC2120 server with Hauppage WinTV-Express card. Kernel is 2.6.10-1.766_FC3 #1

USB camera works just fine. However when I enabled thread for another camera on Composite input on Hauppage card my server dies after a period of time (usually overnight). Needed to cycle power. ....and fsck on VolumeGroup00 now as well.....

It was complaining about "Kernel panic - not syncing mm/slab.c" Then later it was kernel panicking but no longer the message re slab.c

Environment

Motion version: 3.1.18
ffmpeg version: compiled without
Libraries: curl, xmlrpc, ffmpeg, mysql, postgresql
Server OS: FC3

Answer

This is PCI bus related and nothing to do with Motion or v4linux but an issue with Hauppage WinTV-Express card timing on the PCI bus of certain motherboards like that on the HP TC2120 server.

My HP TC2120 has only one suitable slot (the blue one) its a 5 volt PCI bus slot which is 64/32 bit. Its listed as slot 5 with automatic interupt 11.

Upgraded the TC2120 BIOS to the latest version.

Then found this URL

and dropped my latency on PCI from 30 to 10 (mircoseconds I think the units are).

That seems to have fixed it as it did not crash lastnight. Fingers (and toes) crossed!
