An update on the problems I mentioned a few weeks ago about frequent hard lockups without oopses with an AVERMedia board. I finally tracked down the problem - disabling high memory support (ie, support for up to 4GB of RAM) fixes things just dandy. I have 1GB of RAM so I suspect I'm hitting some odd DMA issue that doesn't show up with everybody else's systems, since very few V4L2 users probably have this much memory. Now crashes are almost unheard of - I saw once a day ago, but that's after several dozen captures, so things are still orders of magnitude more stable than they used to be. Even 640x480 captures work great. But I am living with 128MB less system memory than I used to (Linux now maxes out at 896MB), and I'd like to get this fixed long-term. Unfortunately, I'm still not producing oops's. Gerd, I'm willing to spend some time debugging the driver, where should I start? I can get a serial console working but it'll be a week or two. btw, recap on specs: 850Mhz celeron, 1G PC100, BX mobo, linux 2.4.21-pre3, Debian sid, gcc 3.2.2 prerelease, GF2MX video, sblive sound, ATA33 hard disks, no IRQ sharing, ACPI disabled in kernel. bttv 0.9.4 with v4l2 kernel patches. -- Rich Tollerton <rtollert@xxxxxxxxxxxxxxx>
