I have noticed that I can hard lock my system if I start seeing these and the drive doesn't come back quick enough.
ivtv0: All encoder MPEG stream buffers are full. Dropping data. ivtv0: Cause: the application is not reading fast enough. Basically, all I have to do to make it happen is run something hard drive intensive like updatedb and hit a tuner at the same time. I understand the message and the methodology and logic seems totally reasonable, it has to go somewhere. But it shouldn't result in a frozen kernel should it? Anybody have any idea's what I can do to basically save the kernel from this? >From Debian etch running kernel 2.6.18-3-686, no cpuspeed, no smp irqbalancer on a non-hyperthreading p4 with SIS chipset. BTW, there is also a HD-3000 in this system, under the same scenario it appears to recover the stream as expected. I also seem to recall this didn't happen when I was running an older kernel with an older 0.4.x version, but it has been a number of months. Let me know if there is any additional info I can give. ivtv: ==================== START INIT IVTV ==================== ivtv: version 0.8.2 (tagged release) loading ivtv: Linux version: 2.6.18-3-686 SMP mod_unload 686 REGPARM gcc-4.1 ivtv: In case of problems please include the debug info between ivtv: the START INIT IVTV and END INIT IVTV lines, along with ivtv: any module options, when mailing the ivtv-users mailinglist.
