greetings. i recently installed freebsd 8.0 (amd64) on zfs and there is problem: i can't use all installed 4GB memory. i have 2x2GB modules of Kingston DDR2-800
uname -srm
dmesg | grep memory
sysctl -a | egrep 'hw\.[a-z]*mem'
the whole dmesg output:
system were installed according to this guide (without sysinstall):
http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot
does anyone know how may i solve it? thank you.
