My latest attempt to troubleshoot the freezes was to snatch the SATA card out of the box. The machine has been running without any problems since. That was six days, 12 hours ago - the longest uptime I've had since I upgraded the machine to version 6. The only reason I added the SATA controller to the box was to set up a gmirror to make backups to, and since the machine kept freezing all the time I couldn't make decent backups anyway, so removing the SATA card didn't change the machine's duties at all. The reason I suspected the card might be the problem is that I installed it at the same time I upgraded to FreeBSD 6 (when the problems started), the card only cost $20, and the drives attached to the card were getting corrupted during crashes even though they weren't in use. The card was a SYBA SD-SATA-4P. I've also got an rl0 ethernet interface on the PCI bus also, and I wondered if it might be some kind of bus-mastering conflict or something. I still don't know if the problem was bad cheap hardware, bad interactions between cheap hardware, or a software problem. I suppose downgrading to 5.4 again might give some clues, but I don't really want to do that right now since the system finally seems to be stable again, albeit without my large disk array. This may easily have nothing to do with your problem, since we have so little information to go on, but the symptoms sound the same.
