It appears that this problem fits a well-known pattern. See the section "Hardware-specific problems" in the video4linux wiki at
http://linuxtv.org/v4lwiki/index.php/Bttv_devices_%28bt848%2C_bt878%29 copied below for convenience. I put the capture card in a different PCI slot and it seems to work so far. Other postings (sorry, I forgot where) have vague suggestions about changing PCI parameters in the BIOS---literally nothing more specific than that. ----------------------- from http://linuxtv.org/v4lwiki/index.php/Bttv_devices_%28bt848%2C_bt878%29 * bttv + DRI seem not to play nicely together with some cards (ATI Rage128). The linux box just freezes. Don't know why. Suspect it's either a hardware problem or a bug somewhere in DRI (either kernel or xfree86). The only workaround I know of is to turn off DRI. * Some motherboard chipsets have PCI bugs, especially with PCI-PCI transfers which are used for video overlay. The bt848/878 chips have some bug compatibility options, which can be enabled to workaround these problems. Have a look at the triton1 and vsfx insmod options. For some known-buggy chipsets these are enabled automagically. * Sometimes IRQ sharing causes trouble. It works most of the time, but in combination with some hardware and/or drivers it doesn't work. Especially graphic cards are known to cause trouble due to the lack of a IRQ handler. Try disabling the VGA IRQ in the BIOS. Try moving cards to another PCI slot. Your motherboard manual should tell you which PCI slots share IRQ's. -- kernel hangs when running Zoneminder https://bugs.launchpad.net/bugs/260486 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
