If I cat /dev/dv1394-0 > /dev/null (with DV coming in), it generates a whole lot more. Other, possibly related problems: 1) After cat runs for a while, I get "dv1394: discontinuity detected, dropping all frames" 2) heavy hard drive usage tends to freeze processes permanently in D state. Sometimes a strace of 'sync' shows that sync() never returns, even if no other process is stuck in D state yet. I'm using netconsole, and no messages show up in conjunction with this. Alt-SysRq-b seems to be the only way out.
