Hello, Hope I'm on the right list for this...
I'm trying to debug a problem with new PVR-350's. Both a friend of mine and I bought them, built similar (but not same) boxes, and have debian (KnoppMyth), and in my case, I'm now on Kernel 2.6.10 + ivtv 0.3.2d. I've tried both 0.2latest and 0.3 ivtv versions, every firmware version I could get ahold of, every trick I can think of to no avail, so I figured it was time to ask the pros. Our problem is, no matter what ivtv driver we try, or what config options, etc, the boxes lock up spontaneously. The only "temporary" resolution we've been able to make work is to run X (mythfrontend) on a monitor, but still use ivtv to record/playback TV. So, it makes us assume that the lockup/pause/freeze issue has to do with ivtv_fb more than anything else. I've also experienced issues where it will unfreeze after about 10 seconds, only to freeze moments later. Another way to make it lock up is actually playback a recording, and either wait about 2-15 minutes, or ff/rew a couple times. Does the same thing, and if I'm not mistaken, that doesn't even use ivtv_fb... Another oddity is, if I'm SSH'd into the box, sitting at the shell, I can hit enter right after it freezes to unlock it. If I wait too long though, the whole box seems to lock up and my SSH will drop. Can't reconnect, can't anything, have to power cycle. Obviously, this situation makes it rather impossible to use the boxes on just a TV alone. Is anyone familiar with this issue, and or know a way to fix it? I thought maybe it has something to do with IRQ/DMA stuff, and I saw another post asking about that, but no conclusive answers. :( Is it possiable the bus is being flooded with too much I/O? We also thought maybe it has some weirdness w/ the kernel's framebuffer and ivtv's framebuffer conflicting somehow, I even tried compiling my kernel without the console framebuffer, but that just seemed to break everything. Lastly, upgrading from ivtv 0.2 latest to 0.3.2d, now the tuner tunes nothing but static, but I'm way less worried about that since it locks up so much. Here's my dmesg stuff if it helps: Linux video capture interface: v1.00 ivtv: ==================== START INIT IVTV ==================== ivtv: version 0.3.2 (d) loading ivtv: Linux version:
