when the system locks up I get no signal on the monitor, and thus can't see what happened. I've left a SSH session open to /var/log/messages, but there's nothing there except for errors like below: Apr 23 21:44:59 glutton kernel: bttv0: OCERR @ 7a807014,bits: HSYNC OFLOW FBUS FDSR OCERR* >Is an Oops on panic dumped to >the screen, and if so, can you transcribe all the info?

The monitor has no signal, and I can't get to anything. Keyboard numlock doesn't respond. > I'm running a PVR-350 and a LMLBT44. when > > I'm running mythtv AND zoneminder, I get errors along the lines of: > > > > Apr 23 21:44:59 glutton kernel: bttv0: OCERR @ 7a807014,bits: HSYNC > > OFLOW FBUS FDSR OCERR* (which seem to be tied to video capture from > > the PVR-350. > >Well, no, that would be the bttv driver as indicated by the "bttv0:" in >the message. Perhaps, but it seems like I get that error message when the PVR/Mythtv is recording when ZM is running. I suppose it could be from ZM (capturing when I don't expect it to be), but it's always seemed to correlate more to mythtv running. >The best course of action for you, since from past experience I know the >BT878 seems a little sensitive to the quality of PCI bus signal >voltages, is to remove all your PCI cards, blow the dust out of the >slots and reseat all your PCI cards.

Ok, I'll try that. thanks! rick PS The system has only two pc slots, and I've been reluctant to switch the cards because hte ventilation is "Better" with the cards in 1,2 instead of 2,1. could switching pci slots be a valid way to fix? _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
