* v4l bttv bt878 PCI on VIA KT133 chipset crashes? @ 2003-04-05 7:56 Benson Chow 2003-05-04 21:21 ` David J. M. Karlsen 0 siblings, 1 reply; 3+ messages in thread From: Benson Chow @ 2003-04-05 7:56 UTC (permalink / raw) To: linux-kernel Just wonderring. I'm getting weird crashes with running the bttv driver that comes with 2.4.20 (0.7.96?) with a bt878 card. I can record fine from it, can change channels, etc. - Great. Except if I keep on starting and stopping mencoder (opening and closing /dev/video), it usually works for a few times from a fresh reboot just fine, but after 5 times (and it's random, it may not start till after 20 times) it *seems* other parts of kernel space gets badly corrupted. My kswapd oopses and dies. Processes cause oopses for no reason. The oopses tend to occur in disk i/o routines, not in the bttv driver for some reason, and after the corruption (?) occurs, all processes can and will die. The machine eventually goes down hard needing a jab at the case Not exactly a graceful shutdown! The machine seems to work fine if I never use the video capture card, even thrashing disk and flooding the PCI network card seems to work fine. I'm wonderring if anyone else is seeing this issue. Since don't have Windows on this machine nor even have a driver for this card that works for any recent version of windows, I don't know if this is linux specific or not. My guess is it isn't (and it's some hardware incompatibility issue) but I'd like to confirm this - anyone else have this issue? Thanks, -bc WARNING: All HTML emails get deleted.

I had problems with 2.4.20 with the same hardware and using the program zapping for viewing. My box just froze. I thought maybe it was caused by sharing interrupts - but the machine hasn't frozen yet when I switched over to using xawtv instead. ints: david@skunk:~$ cat /proc/interrupts CPU0 0: 29393376 XT-PIC timer 1: 32 XT-PIC keyboard 2: 0 XT-PIC cascade 5: 3529723 XT-PIC ide2, ide3, bttv 8: 4 XT-PIC rtc 10: 119935 XT-PIC usb-uhci, usb-uhci, advansys 11: 2597210 XT-PIC via82cxxx, aic7xxx, eth0 14: 2243192 XT-PIC ide0 15: 2136742 XT-PIC ide1 NMI: 0 LOC: 29394447 ERR: 8021 MIS: 0 david@skunk:~$ HW: david@skunk:~$ lspci 00:00.0 Host bridge: VIA Technologies, Inc.

Karlsen; +Cc: linux-kernel David, I've subsequently found out that the via KT133 sucks, and there's not much that can be done. I replaced it with a (somewhat newer Via) P4X333 chipset motherboard (difference CPU of course) and the driver works perfectly fine. I've heard that the KT133 and a lot of via's older chipsets cannot handle multiple busmasters on PCI transactions properly. I suspect disabling DMA on the harddrive may fix the problem, but I have not looked into this possibility as I got the new machine. Hope this enlightens... -bc On Sun, 4 May 2003, David J. M.
