During the final step of that procedure DRAC resets itself in order to load the new certificate. The result of DRAC's reset was a kernel panic of the 7.3-RELEASE amd64 that runs on that system. The panic messages seem to be USB related and are available at: http://noc.ntua.gr/~christia/2010-06-16_163545.png The memory dump completed successfully(?) but the subsequent kgdb backtrace failed with the following output: # kgdb /boot/kernel/kernel /var/crash/vmcore.0 GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
