Stephen, does the problem *only* happen when using the -d flag, or does the system lock up on reboot in general? If the latter, try using one or both of the following sysctls: hw.acpi.handle_reboot=1 hw.acpi.disable_on_reboot=1 If the lesser, I've no idea. The problem only happens when I do the reboot -d. If I do reboot it comes back ok. I have tried it on two different platforms 1) a Biostar TForce 6100 mainboard with an AMD dual core processor 2) a Soekris net5501 with the same results. I get the dumping message and then it hangs and I have to hard reset the box. Thanks, Steve -- They that give up essential liberty to obtain temporary safety, deserve neither liberty nor safety.

6.3 reboot -d doesn't work
Hello List, I am trying to get a crash dump but am unable to with FreeBSD 6.3-RELEASE-p2 /etc/defaults/rc.conf dumpdir=/var/crash# Directory where crash dumps are to be stored savecore_flags= # Used if dumpdev is enabled above, and present.
