I have several experiences that sudden reboot is happened just after "fwcontrol -R foo.dv" was invoked. The operating system is FreeBSD 7.2R/i386. Before I use 7.2R, I used 6.3R and I never experienced such phenomenon. The sudden reboot is not always occurred. The probability is less than 1/200, when I randomly used "fwcontrol -R". However, there seems to exist the condition that the probability is considerably high. I used the PC as a video recorder with two firewire bus, and each bus connects to video capture box (in total two capture box). I record several programs at Sunday morning, and I met a sudden reboot at 8:30am with probability higher than 1/2. The recording schedule is as follows. 06:30:00.00 - 06:28:11 fwcontrol -u 0 -R 07:00:00.07 - 07:26:26 fwcontrol -u 0 -R 07:00:45.00 - 07:28:16 fwcontrol -u 1 -R 08:00:00.00 - 08:29:58 fwcontrol -u 0 -R 08:29:59.93 - 08:57:26 fwcontrol -u 0 -R 08:30:00.08 - 08:58:46 fwcontrol -u 1 -R The one of the two last fwcontrol seems to cause a reboot. I tried the following procedure several times. [offset] [duration] [command] 00:00:00 - 58 sec fwcontrol -u 1 -R 00:01:00 - 58 sec fwcontrol -u 0 -R 00:02:00 - 58 sec fwcontrol -u 0 -R 00:02:00 - 58 sec fwcontrol -u 1 -R I only met one reboot. I wander how to identify the reason. Do you have any suggestion to find (and fix) the reason (or problem)? Best regards, Kazumaro Aokihome | help
