I hope you're not using a Natoma chipset based motherboard (P6) - it hates the Meteor card. :-) > I have reboot problems for no apparent reasons. > The rebooting occurs about every 3-4 days.

Well, you should certainly enable crash dumps, so that if it's panic'ing you can at least see where. If it's possible for you to be at the console when it dies, you can also enable DDB and simply debug it interactively when it happens (sometimes nicer in the really odd "only happens when process x is running" cases). See /sys/i386/conf/LINT for the appropriate kernel options and /etc/sysconfig for the options for enabling crashdumps. > I am also thinking of directing the reboot error > messages onto /var/log files, via syslogd.

Well, absolutely nowhere do you say which *version* of FreeBSD you're running, so it's impossible to even guess. :-) -- - Jordan Hubbard FreeBSD core team / Walnut Creek CDROM.
