My mythtv backend system became completely unresponsive last night during a scheduled record. My syslog is now 150M with "ENC Stream 0 OVERFLOW" messages as it was running like this all night. I had to reboot.
Is there anyway I can help debug this? Does this help? ivtv: version 0.4.0 Encoder revision: 0x02050032 kernel 2.6.14-1.1637_FC4 Dec 16 00:48:36 nelson kernel: ------------[ cut here ]------------ Dec 16 00:48:36 nelson kernel: kernel BUG at lib/radix-tree.c:276!
