It seems pretty similar to the previous one. BTW, here it is:
Loading /boot/defaults/loader.conf
/boot/kernel/kernel data=0xfe0c70+0x3fded0 syms=[0x8+0x13d310+0x8+0x13c5de]
/boot/entropy size=0x1000
Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [/boot/kernel/kernel] in 6 seconds...
Type '?' for a list of commands, 'help' for more detailed help.
OK boot -v
Booting...
